  2. Amoghavarsha I built the magnificent rock-cut monolithic Kailasa temple at Ellora.

Which of the statements given above is/are correct?

Detailed Solution for UPPSC AE Civil Prelims Mock Test - 1 - Question 1

The correct answer is A. 1 only

The Rashtrakutas were indeed of Kannada origin, with Kannada as their mother tongue, making statement 1 correct. However, the rock-cut monolithic Kailasa temple at Ellora was constructed by Krishna I, not Amoghavarsha I, thus rendering statement 2 incorrect.

Details on Other Options:

  • B: This option is incorrect because while statement 2 is false, statement 1 is accurate, which means only statement 1 is correct.
  • C: This option is incorrect as it claims both statements are true, but statement 2 about Amoghavarsha I is incorrect.
  • D: This option is incorrect because it dismisses both statements, whereas statement 1 is confirmed to be correct.

Conclusion:

Option: A, as the most accurate choice, highlights the correct assertion about the Rashtrakutas' origins while clarifying the inaccuracy regarding the temple's builder. Thus, 1 only is the correct answer.

UPPSC AE Civil Prelims Mock Test - 1 - Question 3

Zero hour in political jagron referes to

Detailed Solution for UPPSC AE Civil Prelims Mock Test - 1 - Question 3

The correct answer is D. question-answer session

Zero hour in political terminology refers specifically to the question-answer session that occurs in Parliament. It begins immediately after the question hour and lasts until the day’s agenda is addressed. This time, typically starting at 12 noon, allows Members of Parliament (MPs) to raise urgent public issues. Although not formally outlined in procedural rules, Zero hour is a unique feature of Indian parliamentary practice established in 1962.

Details on Other Options:

  • A: This option is incorrect because it describes a day when no parliamentary business occurs, which does not align with the definition of Zero hour.
  • B: Suspended motion is not relevant to Zero hour, as this term refers to a motion that is temporarily halted and does not pertain to the question-answer session.
  • C: Adjourned time refers to a pause in proceedings, which is distinct from Zero hour that specifically allows for questions on urgent matters.

Conclusion:

Option: D, as the most accurate and relevant choice, clearly represents the function of Zero hour in Parliament, distinguishing it from the other options. Thus, question-answer session is the correct choice.

UPPSC AE Civil Prelims Mock Test - 1 - Question 4

Consider the following statements

1. All industrial projects require environmental clearance by an expert committee formed by Centre

2. An Environmental impact assessment (EIA) is mandated under the Environment Protection Act, 1986

Which of the above statements is/are correct ?

Detailed Solution for UPPSC AE Civil Prelims Mock Test - 1 - Question 4

The correct answer is 2 only.

  • The Environmental Impact Assessment (EIA) is one of the cornerstones of ensuring that the ecological costs of infrastructure development are minimal.
  • Prospective projects above a certain size and with a potential to significantly alter the natural environment must be first approved by the State Environment Impact Assessment Authority (SEIAA) comprising State officers and independent experts. Hence, Statement 1 is not correct.
  • Projects that are even bigger or involve forest land — category A — must be cleared by an expert committee formed by the Centre.
  • SEIAA projects make up the bulk of projects for approval including building and construction, small mining, and small industrial projects, and are considered ‘less polluting’.

Applicability in India

  • EIA was first introduced in 1978 with regard to the various river valley projects all over the country and later expanded to include various other developmental procedures in its scope. EIA is now mandatory for over 30 classes of projects.
  • The Environmental Protection Rules, 1986 warrant for the imposition of certain restrictions on the construction/ expansion/ modernization of specific projects without prior approval from the Central, State, or Union Territory level Environmental Impact Assessment Authority (EIAA) constituted under the Environment Protection Act, 1986. Hence, Statement 2 is correct.

Categorisation of projects

  • The rules categorise the projects into two categories- A and B on the basis of the magnitude of their scale and impact on the natural and artificial resources.
  • The projects belonging to Category A require approval from the Ministry of Environment and Forests on behalf of the Central Government, on the advice of an Expert Appraisal Committee (EAC), constituted by the Central Government for this specific purpose; eg. Construction or Expansion of Ports, harbours, airports, nuclear power, and related projects, Primary metallurgical industries (iron, steel, copper, etc), individual projects, etc.
  • Projects and Activities falling under Category B require the approval of a State EIAA, based on the advice of a State Expert Appraisal Committee (SEAC), constituted under the said notification.
UPPSC AE Civil Prelims Mock Test - 1 - Question 5

Which one of the following options correctly matches column - I to that of column - II?

Detailed Solution for UPPSC AE Civil Prelims Mock Test - 1 - Question 5

The Correct answer is (i) - (B), (ii) - (D), (iii) - (C), (iv) - (A)
Explanation:

Xylem:

  • The xylem is a specialized tissue in plants responsible for transporting water and minerals from the roots to the leaves and other aerial parts of the plant. It is a unidirectional flow, from the roots to the aerial parts, driven by transpiration (evaporation of water from the leaves) and capillary action.

Phloem:

  • The phloem is another specialized tissue in plants responsible for the translocation of food materials, such as sugars and other organic compounds, from the leaves (source) to other parts of the plant, like roots, stems, and developing fruits (sinks).

Root hair:

  • Root hairs are small, finger-like extensions of root epidermal cells. They significantly increase the surface area of the roots, facilitating the absorption of water and minerals from the soil. Root hairs play a crucial role in the absorption of water and nutrients needed for plant growth.

Stomata:

  • Stomata are tiny pores found primarily on the surface of leaves and sometimes on stems. They regulate the exchange of gases (such as carbon dioxide and oxygen) and water vapor between the plant and the atmosphere.
  • Stomata facilitate the entry of carbon dioxide for photosynthesis and the release of oxygen. During this process, water vapor is also lost through transpiration, contributing to the movement of water and minerals through the xylem.

UPPSC AE Civil Prelims Mock Test - 1 - Question 16

Which one of the following is NOT a greenhouse gas?

Detailed Solution for UPPSC AE Civil Prelims Mock Test - 1 - Question 16

The correct option is CO (Carbon Monoxide).
Explanation:
Greenhouse Effect:

  • Solar energy is trapped by the earth atmosphere and radiate slowly so to cover our earth with a warm blanket.
  • This is the natural process of the greenhouse effect on earth to maintain its temperature and makes the earth perfect for life.

Greenhouse gases are carbon dioxide, other greenhouse gases are methane, water vapour, nitrous oxide, CFCs and ozone.
Values of radiation absorbed by the greenhouse gases
are as follow:

From the above table, it is clear that carbon dioxide absorbs the maximum radiation in the earth’s atmosphere
Hence the correct option is Carbon Monoxide (CO) which is not a greenhouse gas.
The major greenhouse gases are

  • Water vapour - causes about 36% - 70% of the greenhouse effect
  • Carbon dioxide (CO2) causes 9 - 26%
  • Methane (CH4) causes 4 - 9%
  • Ozone (O3)
  • Nitrous Oxide
  • Chlorofluorocarbons (CFCs)

Important Points
Global warming:

  • If the number of greenhouse gases crosses by delicate proportion, the natural greenhouse balance may get disturbed and there is a continuous rise in the temperature of the earth by trapping the solar heat continuously.
  • This creates the overall effect of Global warming.
UPPSC AE Civil Prelims Mock Test - 1 - Question 17
What are the components of ICT?
Detailed Solution for UPPSC AE Civil Prelims Mock Test - 1 - Question 17

The correct answer is C. Hardware, Software, User, Network

Information and Communication Technology (ICT) encompasses the technologies used for processing and communicating information. It involves the use of electronic computers and software for converting, storing, protecting, processing, networking, transmitting, and retrieving data. ICT is defined as the skills related to computing devices, the software that operates them, the applications they run, and the systems built with these technologies.

Details on Other Options:

  • A: This option is incorrect because system software and operating systems are components of software, not a complete representation of ICT.
  • B: While input, output, storage, and memory devices are part of computer systems, they do not encompass the full scope of ICT, which includes users and networks as well.
  • D: Although computers, the internet, and projectors are related to ICT, this option does not cover the fundamental components like hardware, software, and users.

Conclusion:

Option: C, as the most accurate and relevant option, stands out for its comprehensive coverage of the essential components of ICT, clearly differentiating it from the other options. Thus, Hardware, Software, User, Network is the correct choice.

UPPSC AE Civil Prelims Mock Test - 1 - Question 18

Detailed Solution for UPPSC AE Civil Prelims Mock Test - 1 - Question 18

The principle or rule of beneficence refers to a normative statement of a moral obligation to act for the others’ benefit, helping them to further their important and legitimate interests, often by preventing or removing possible harms.

That means all our thoughts and actions must be directed to ensure that others benefit from these thoughts and actions.

Example: When apparel manufacturers are criticized for not having good labour practices in factories, the ultimate goal of the criticisms is usually to obtain better working conditions, wages, and other benefits for workers.
UPPSC AE Civil Prelims Mock Test - 1 - Question 19
The tendency to over - rate an employee's performance is known as
Detailed Solution for UPPSC AE Civil Prelims Mock Test - 1 - Question 19

The correct answer is B. Halo Effect

The halo effect refers to the tendency to overestimate an employee's performance based on a single positive trait. This cognitive bias occurs during performance appraisals, where evaluators may let one favorable characteristic influence their overall judgment of an employee's capabilities. For instance, if an employee is perceived as friendly, the evaluator might assume they are also competent, leading to inflated performance ratings.

Details on Other Options:

  • A: This option is incorrect because the positive effect generally refers to the tendency to rate individuals favorably based on a specific positive trait but does not specifically denote performance appraisal bias.
  • C: The Hawthorne effect is not relevant here; it describes a change in behavior when individuals know they are being observed, rather than an overestimation of performance.
  • D: Biasness is a broader term for favoritism in judgment but does not specifically pinpoint the phenomenon of overrating performance based on a singular trait.

Conclusion:

Option: B, as the most accurate and relevant option, highlights the specific cognitive bias in performance assessments, clearly distinguishing it from the other options. Thus, Halo Effect is the correct choice.

UPPSC AE Civil Prelims Mock Test - 1 - Question 20

Which of the following statements is INCORRECT regarding a thermodynamic system?

Detailed Solution for UPPSC AE Civil Prelims Mock Test - 1 - Question 20

Explanation:
Thermodynamic system:

  • A thermodynamic system is a region of space containing a quantity of matter that is distinct from its surroundings and can be the subject of thermodynamic study.
  • The study of thermodynamic systems is a fundamental part of thermodynamics, which is a branch of physics that deals with the relationships and transformations of energy within a system.

Thermodynamic systems are classified into different types:
Open System:

  • In this type of system, both mass and energy, transfer takes place across the boundary of the system.
  • Examples include pumps, compressors, reactors, distillation columns, heat exchangers, car radiators, etc.

Closed System:

  • There is no mass transfer across the system boundary, but energy transfer takes place in or out of the system.
  • Examples: A gas confined within a piston-cylinder arrangement, A hot water tank in a residential heating system, The combustion process that occurs within a car engine, A sealed container filled with a gas, The refrigeration cycle in a household refrigerator or air conditioner, etc.
  • The contents of a pressure cooker on a stove with its lid tightly closed and the whistle in position is a closed system as no mass can enter or leave the pressure cooker, but heat can be transferred to it.
  • A bomb calorimeter only allows heat to be exchanged. Such a system is called closed.

Isolated system:

  • In an Isolated system, there is no mass and energy interaction across the system boundary i.e. Interaction between the system and the surroundings is absent.
  • Therefore, mass and the energy of the isolated system are fixed e.g. Universe, A well-insulated thermos flask, Liquid nitrogen stored in a sealed and insulated container, etc.

Surroundings:

  • The surroundings, also known as the environment, represent everything outside the system boundaries.
  • This includes the external conditions that can influence the system.
  • The surroundings are essential for defining the energy interactions of a system.
  • For example, if a gas is expanding in a cylinder, the surroundings include the walls of the cylinder and the external environment.

Boundary:

  • The boundary is the interface that separates the system from its surroundings.
  • It can be real or imaginary, and it can allow for the exchange of energy and/or matter.
  • The nature of the boundary defines whether the system is isolated, closed, or open
  • In thermodynamics, the system boundary can be classified as either movable or fixed, and this distinction is important in understanding how the system interacts with its surroundings.
  • Movable Boundary:
    • In a system with a movable boundary, the physical separation between the system and its surroundings can change. This allows for the expansion or contraction of the system, adjusting the volume it occupies. Movable boundaries are common in systems like pistons and cylinders, where the piston can move to change the volume of the gas inside.
  • Fixed Boundary:
    • In a system with a fixed boundary, the physical separation between the system and its surroundings remains constant. The volume of the system is fixed, and there is no movement of the boundary. Fixed boundaries are typical in systems like closed containers or rigid tanks.

UPPSC AE Civil Prelims Mock Test - 1 - Question 23

Which Control chart shows fraction defective?

Detailed Solution for UPPSC AE Civil Prelims Mock Test - 1 - Question 23

Explanation:
P-chart (Proportion or Fraction Defective Chart):

  • It is used to monitor and control the fraction produced in a process that is defective or non-conforming.
  • It follows a binomial distribution.
  • This chart is best suited in cases where inspection is carried out to classify articles as either excepted or rejected.

Fraction defective = (Number of defective articles)/(Size of sample) ⇒ P = ∑d/N
Working rule

  • Calculate the average fraction defective.
  • Compute σ the standard error of fraction defective.
  • Standard error of  (σp) =   
  • Now calculate both the limits.

Additional InformationControl charts:

  • A control chart is a graphical representation of the collected information.
  • It indicates whether a process is in control or out of control.
  • It determines process variability and detects unusual variations taking place in a process.
  • It ensures the product quality level.
  • It provides information about the selection and setting of tolerance limits.

Types of Control Charts:
Variable charts
are meant for the variable type of data. X bar and R Chart, X bar and sigma chart, the chart for the individual units
Attribute charts are meant for attribute type of data. p chart, np chart, c chart, u chart, U chart.

Control charts for the variable type of data (X bar and R charts)

  • In the x bar chart, the sample means are plotted in order to control the mean value of a variable.
  • In the R chart, the sample ranges are plotted in order to control the variability of a variable.
    • R charts are used to monitor the variation of a process based on samples taken from the process at given times (hours, shifts, days, weeks, months, etc.).
    • The measurements of the samples at a given time constitute a subgroup.

Control charts for Attribute type data (p, c, u charts)

  • p-charts calculates the percentage defective in the sample; p-charts are used when observations can be placed in two categories such as yes or no, good or bad, pass or fail etc.
  • c-charts counts the number of defects in an item; c-charts are used only when the number of occurrences per unit of measure can be counted such as the number of scratches, cracks etc.
  • u-chart counts the number of defects per sample; The u chart is used when it is not possible to have a sample size of a fixed size.

  • The word ‘ceramic’ meant for burnt material
  • Low hardness is a characteristic property of ceramic material
  • With sintering, the grain boundary and bulk atomic diffusion contribute to densification, surface diffusion, and evaporation condensation can cause grain growth but does not cause densification. After pressing, ceramic particles touch one another.
UPPSC AE Civil Prelims Mock Test - 1 - Question 25

Identify the odd one out of the following processes.

Detailed Solution for UPPSC AE Civil Prelims Mock Test - 1 - Question 25

Explanation:

Welding process:

  • Welding is a fabrication process whereby two or more parts are fused together by means of heat, pressure or both forming a join as the parts cool. Welding is usually used on metals and thermoplastics but can also be used on wood. The completed welded joint may be referred to as a weldment.

Classification of welding process:

Manual Metal arc welding (MMAW, Metal stick & SMAW):

  • Manual metal arc welding (MMA or MMAW), also known as shielded metal arc welding (SMAW), flux shielded arc welding or stick welding, is a process where the arc is struck between an electrode flux coated metal rod and the workpiece. Both the rod and the surface of the workpiece melt to create a weld.

Submerged arc welding:

  • Submerged Arc Welding creates the electric arc beneath a bed of flux powder, which provides shielding gases and slag as well as alloying elements for the molten pool.
  • The flux layer drastically reduces heat loss and works as an automated or semi-automated process. A hopper recycles the excess flux and slag layers are removed after welding.

Out of the given four options, Submerged Arc Welding is the odd one out.

UPPSC AE Civil Prelims Mock Test - 1 - Question 27

Cavity type tube well is suitable for:

Detailed Solution for UPPSC AE Civil Prelims Mock Test - 1 - Question 27

Explanation:
Wells can be classified as:
1) Strainer type tube well:

  • It is the most commonly used type of tube well in our country.
  • It is so common that whenever we talk of a tube well, it is automatically understood to refer to a strainer-type tube well.
  • This tube well consists of blind pipes and strainer pipes or screen pipes.
  • This tube well is generally unsuitable for very fine sandy strata, because in that case, screen openings are likely to get choked easily.

​2) Cavity type tube well:

  • A cavity-type tube well consists of a pipe sunk into the ground and resting on the bottom of a strong clay layer. It does not utilize stainers and hence it draws its supply from the bottom and not from the sides.
  • In the initial stages of pumping fine sand comes out with water and consequently, a cavity is formed at the bottom.
  • The water from the aquifer enters the pipe through the cavity and as the pumping continues, the spherical area of the cavity increases outwards with result that the velocity flow being reduced and consequently sand stop entering the well pipe.
  • Hence, in the beginning, sandy water is obtained, which clears out with time.

3) Gravel pack type tube well:

  • A Gravel pack type tube well (slotted type tube well) consists of a pipe which is slotted for part of its length at one end and for the rest of the length it is plain pipe
  • In order to prevent the fine sand particles entering the well pipe, it is surrounded by a mixture of gravel and coarse sand (bajri). The mixture of gravel and coarse sand placed around the well pipe is called shrouding, and it is poured from the top into the annular space between the well pipe and the casing pipe before withdrawing the casing pipe.

UPPSC AE Civil Prelims Mock Test - 1 - Question 29
________ is the small area network that covers small geographical area.
Detailed Solution for UPPSC AE Civil Prelims Mock Test - 1 - Question 29

The correct answer is LAN. (Local Area Network)

A Local Area Network (LAN) is designed to cover a small geographical area, typically limited to a few kilometers. It is privately owned and ideal for environments such as offices, homes, hospitals, and schools. LANs are straightforward to design and maintain, minimizing errors and noise due to their short-distance coverage. They facilitate the sharing of data, tools, and programs among connected devices, typically through a switch or a stack of switches, using a private addressing scheme as defined by the TCP/IP protocol. Routers are utilized at the LAN's boundary to connect it to larger Wide Area Networks (WANs).

Details on Other Options:

  • A: A Wide Area Network (WAN) spans a large geographical area, often connecting multiple LANs through various communication methods, such as telephone lines, making it unsuitable for small area coverage.
  • B: A Metropolitan Area Network (MAN) covers a larger area than a LAN but is smaller than a WAN, typically connecting multiple LANs within a city or region, thus not fitting the definition of a small area network.
  • D: A Bridge is a device used to connect and filter traffic between two or more LAN segments, but it is not a network type itself and does not define a geographical area.

Conclusion:

Option: LAN, as the most accurate and relevant option, stands out for its specific application in small geographical areas, clearly differentiating it from the other options. Thus, Local Area Network is the correct choice.
