UPSSSC JE Mechanical Paper 1 Mock Test - 2 - Mechanical Engineering MCQ

The correct answer is: Rohit asked me, ‘Did you see the cricket match on TV last night?’

Key Points

• The given sentence is in indirect speech and we need to convert it to direct speech.
• When we change an indirect speech to direct speech, we must follow these rules:
  • The reporting verb 'asked' remains unchanged.
  • “If” is the conjunction we use in indirect speech when we report yes/no questions.
  • A comma (,) is added after the direct speech part.
  • The first word of the direct speech is in capital letters.
  • 'Previous night' changes to 'Last Night.'
• Thus, option 1 is the correct answer.
  

Hence, direct speech is- Rohit asked me, ‘Did you see the cricket match on TV last night?’

The correct answer is ‘All the biscuits were eaten by the mouse from the tin.’

Key Points

• The given sentence is in active voice. As per the question we have to change it into passive voice.
• The structure of the given sentence is as follows:
  • Subject + past tense + Object (Active voice)
  • Subject (objective case) + was/were + past participle + Object (subjective case) (Passive voice)
• Example:
  • She built a big house. (Active voice)
  • A big house was built by her. (Passive voice)
• The subject of the given sentence is ‘The mouse’.
• The object of the given subject is ‘all the biscuits’.
• The subject will be put in place of the object and the object will be put in place of the subject.
• Ate will be changed to were eaten.

Correct sentence - All the biscuits were eaten by the mouse from the tin.

Additional Information

• When converting active to passive voice, it is important to keep in mind that simple past gets converted to past perfect tense.
• In addition to this, it is important to place ‘all’ between the ‘was’ and ‘eaten’.
• This is because adverbs and adjectives tend to split the verb between its main verb and the auxiliary verb.
• To add to this, the placement of the phrase ‘from the tin’ is crucial.
• Since the phrase describes the biscuits, not the mouse, it is important to place the phrase as close to ‘biscuits’ as possible.

'शेखर एक जीवनी'  उपन्यास प्रेमचन्द्र का नहीं है।

‘शेखर एक जीवनी’ महज एक उपन्यास नहीं है और न ही कथानायक शेखर की जीवनी का लेखा-जोखा, वरन् स्नेह और वेदना का जीवन-दर्शन भी है, जिसे लेखक ने अपने जीवनानुभवों के विस्तृत दायरे के सूत्र में पिरोया है। सच्चिदानन्द हीरानन्द वात्स्यायन ‘अज्ञेय’ की यह अमर कृति हिन्दी साहित्य में मील का पत्थर है।

The correct answer is 'I recollect being taken to the circus by my mother'.

Key Points

• The given sentence is in Active Voice. As per the given question we have to change it into Passive Voice.
• The process of transformation is as follows:
  • The given sentence is in the active voice and 'my mother' is the subject and 'circus' is the object.
  • When we convert this sentence into a passive voice, the subject 'my mother' of the active voice becomes the object, the object 'circus' becomes the subject.
  • The passive structure "being + V3 (taken)" should be used.
  • This is the active and passive voice rule for the present continuous tense.
• Therefore, as per the points mentioned above, we find that the correct answer is Option 4.

Correct Sentence: I recollect being taken to the circus by my mother.

Additional Information

• What is Active and Passive Voice?
  • In Active Voice, a sentence emphasizes the subject, performing an action.
  • In Passive Voice, a sentence emphasizes the action or the object of the sentence.

• Verbs of passive format have a different set of tenses (*V3 - Past participle or Third form of the Verb) as given below in the table:

From Statement 1:

No one has exam after S.

Three people has exam between S and R.

N has exam before R.

M has exam after Thursday.

W has exam before B.

From, this statement, we get:

 So, from this statement, N has exam immediately after B.

From Statement 2:

Two people have exam before R, who has exam immediately after S.

B has exam after R but not on Saturday.

N has exam immediately after H.

From this statement, M has exam immediately after B.

So, either statement 1 or statement 2 alone is sufficient to answer the question.

Hence option C is correct.

P sits to the immediate left of S.

Hence, option A is correct.

As Glove is worn in Hands similarly Socks are worn on feet.

Q, R, S, T, U, and V are seated in a straight line facing North.

i) S is second to the right of T.

ii) T is second to the right of Q.

iii) R is to the immediate left of Q

iv) R is to the immediate left of Q and is second to the left of V.

Thus we can see R and S is sitting at the extreme ends.

Hence, the correct answer is "RS".

M is son-in-law of K, brother-in-law of J. It means K is the father/mother of M’s wife. J is brother of M’s wife. Hence J is K’s son.

The correct answer is Fatehgarh Sahib.

Key Points

• The energy crisis is the concern that the world’s demands on limited natural resources are exhausting.
• Resources, like fossil fuels that are used to power industrial society, are diminishing as the demand rises.
• These natural resources are in limited supply.
• While they do occur naturally, it can take hundreds of thousands of years to replenish the stores.
• It has nothing to do with demand and supply but highlights the fact that there are limited resources for use and consumption.

Thus, the energy crisis means the danger of extinction of fossil fuels like coal and petrol.

Important Points

There are basically two sources of energy:

The correct answer is 'Shauraseni Prakrit'.

Key Points

• The Punjabi language is a descendant of the Shauraseni Prakrit.
• It is a language of medieval northern India that was used primarily in drama and plays during the 3rd to 10th centuries.
• It is believed Punjabi developed as an evolution from the Shauraseni-Prakrit-Apabhramsha languages around the 11th century.
• It also has some influence from the pre-Indo-Aryan languages on its phonology and morphology.

A is the correct option.The Jabala Upanishad, also called Jabalopanisad, is a minor Upanishad of Hinduism. The Sanskrit text is one of the 20 Sannyasa Upanishads, and is attached to the Shukla Yajurveda. The Jabala Upanishad is an ancient text, composed before 300 CE. It provides earliest clear reference to the four ashramas of the student, house-holder, forest hermit, and recluse.

The correct answer is It is a closed system.
Key Points

• Ecosystem:
  • Ecosystem, a natural resource system, the complex of living organisms, their physical environment, and all their interrelationships in a particular unit of space.
  • An ecosystem is an open system that can be categorized into its abiotic constituents, including minerals, climate, soil, water, sunlight, and all other nonliving elements, and its biotic constituents, consisting of all its living members. Hence, statement 3 is incorrect.
  • Linking these constituents together are two major forces: the flow of energy through the ecosystem, and the cycling of nutrients within the ecosystem.
  • The fundamental source of energy in almost all ecosystems is radiant energy from the Sun.
  • The energy of sunlight is used by the ecosystem’s autotrophic, or self-sustaining, organisms. Consisting largely of green vegetation, these organisms are capable of photosynthesis i.e., they can use the energy of sunlight to convert carbon dioxide and water into simple, energy-rich carbohydrates.
  • The autotrophs use the energy stored within the simple carbohydrates to produce the more complex organic compounds, such as proteins, lipids, and starches, that maintain the organisms’ life processes.
  • The autotrophic segment of the ecosystem is commonly referred to as the producer level.

Additional Information

• The organic matter generated by autotrophs directly or indirectly sustains heterotrophic organisms.
• Heterotrophs are the consumers of the ecosystem; they cannot make their own food.
• They use, rearrange, and ultimately decompose the complex organic materials built up by the autotrophs.
• All animals and fungi are heterotrophs, as are most bacteria and many other microorganisms.
• Together, the autotrophs and heterotrophs form various trophic (feeding) levels in the ecosystem: the producer level, composed of those organisms that make their own food; the primary consumer level, composed of those organisms that feed on producers; the secondary consumer level, composed of those organisms that feed on primary consumers; and so on.
• The movement of organic matter and energy from the producer level through various consumer levels makes up a food chain.
• For example, a typical food chain in a grassland might be grass (producer) → mouse (primary consumer) → snake (secondary consumer) → hawk (tertiary consumer).
• Actually, in many cases the food chains of the ecosystem overlap and interconnect, forming what ecologists call a food web.
• The final link in all food chains is made up of decomposers, those heterotrophs that break down dead organisms and organic wastes.
• A food chain in which the primary consumer feeds on living plants is called a grazing pathway; that in which the primary consumer feeds on dead plant matter is known as a detritus pathway.
• Both pathways are important in accounting for the energy budget of the ecosystem.

Answer: B. Yerragudi Minor Rock Edict

The Ashokan Rock Edict found written partly in the Boustrophedon style is the Yerragudi Minor Rock Edict. The reasons for this are:

• Boustrophedon style refers to a writing style where alternate lines of text are reversed, with the direction of writing and reading alternating from left to right and then right to left. This style of writing was used in some ancient scripts, such as Greek and Etruscan.
• Yerragudi Minor Rock Edict, also known as the Gavimath inscription, is located in the Koppal district of Karnataka, India. It is one of the earliest inscriptions of Emperor Ashoka, dating back to the 3rd century BCE.
• The inscription is written in the Prakrit language using the Brahmi script, and it contains the early teachings of Buddhism, as well as the principles of Dhamma (righteousness).
• The Boustrophedon style can be observed in some parts of the Yerragudi Minor Rock Edict, making it the correct answer for this question.

The correct answer is '1577'.

Key Points

• Amritsar was founded by Shri Guru Ramdas ji, the fourth guru of the Sikhs in about 1577 A.D.
• Before the city was founded, the area was covered with thick forests and had several lakes.
• The construction of Amrit Sarovar from which the city gets its present name was also started by Shri Guru Ramdas.
• His successor, Shri Guru Arjan Dev, completed the project and located the Harmandir Sahib in its midst.
• Maharaja Ranjit Singh took over full control of Amritsar by 1802 A.D.

• The Kingdom of Anga was indeed a powerful entity before being conquered by Bimbisara, making statement 1 correct.
• Avanti, with its capital at Ujjain, was a significant competitor, partly due to its access to iron deposits, which made it a rival in military capabilities, so statement 2 is correct.
• Magadha's economic prosperity was significantly boosted by its agricultural productivity due to the fertile alluvial soil of the middle Gangetic plain, contrary to statement 3, which underestimates agriculture's role.

The correct answer is Gatka.

Key Points

• The famous martial art form Gatka comes from the Punjab state of India.
• Gatka is basically a battle technique created by Sikh warriors during the war period of Sikh Gurus.
• In this art form mainly weapons like Kirpan, Talwar(Sword), Katar, Shield, and Sotti(Stick) are used.

• Statement-I is correct: The shift towards ritualistic practices and the corruption observed within Buddhist monasteries were significant factors in the decline of Buddhism in India. These developments marked a departure from the principles that initially defined Buddhism, leading to disillusionment among followers.
• Statement-II is correct: This deviation from the foundational teachings of simplicity and austerity, which were directly accessible and appealing to the common people, diluted Buddhism's appeal. The religion's increasing complexity and the perceived moral decline among its clergy made it less attractive to its base of support.
• Statement-II directly explains Statement-I by providing the underlying reason for the decline mentioned in Statement-I. The adoption of complex rituals and the loss of ethical standing among the Buddhist community undermined the religion's foundational appeal, directly contributing to its decline.

Answer:
The correct answer is option C: Speed.
Explanation:
Paper spreadsheets can have many advantages similar to electronic spreadsheets, such as organization and calculation capabilities. However, they lack the advantage of speed that electronic spreadsheets offer. Here is a detailed explanation:
Advantages of paper spreadsheets:
- Rows and columns: Paper spreadsheets can be structured with rows and columns, allowing for easy organization of data.
- Headings: Paper spreadsheets can also include headings, which help to label and categorize the data.
- Manual calculations: Paper spreadsheets can be used to perform manual calculations, just like electronic spreadsheets.
Disadvantage of paper spreadsheets:
- Speed: The main disadvantage of paper spreadsheets is the lack of speed. Performing calculations and making changes on paper can be time-consuming compared to electronic spreadsheets, which allow for instant calculations and automatic updates.
In summary, while paper spreadsheets can have advantages such as rows and columns and headings, they lack the speed offered by electronic spreadsheets.

Additional Information

• A batch file is a text file that contains a sequence of commands for a computer operating system. It's called a batch file because it batches (bundles or packages) into a single file a set of commands that would otherwise have to be presented to the system interactively from a keyboard one at a time.
• Its extention is .bat.

Introduction:
In this question, we are asked to identify the characteristics of a laser printer. We need to choose the correct options from the given choices.
Characteristics of a laser printer:
A laser printer is a type of printer that uses laser technology to produce high-quality prints. Let's analyze each statement given in the question and determine its accuracy:
1. Prints an entire line at a time:
- This statement is true. Laser printers use a process called "electrophotography" or "xerography" to print an entire line at a time. This process involves the use of a laser beam to create an electrostatic image of the entire line on a photosensitive drum.
- Correct
2. Non-impact printer:
- This statement is true. Laser printers are non-impact printers, which means they do not require direct contact between the print head and the paper to create an image. Instead, they use a laser beam to transfer toner onto the paper.
- Correct
3. Allows multiple copies to be taken at a time:
- This statement is false. Laser printers generally do not allow multiple copies to be taken at a time. However, some advanced laser printers may have features like duplex printing or collating, which can produce multiple copies in a single print job.
- Incorrect
4. Prints one character at a time:
- This statement is false. Laser printers do not print one character at a time. As mentioned earlier, they print an entire line at a time using a laser beam and electrostatic imaging.
- Incorrect
Conclusion:
Based on the analysis, we can conclude that the correct characteristics of a laser printer are:
- Prints an entire line at a time
- Non-impact printer
Therefore, the correct answer is (A) i and ii.

Software:
- Software refers to a collection of programs, data, and instructions that enable a computer system to perform specific tasks or functions.
- It is a set of instructions that tells the computer what to do and how to do it.
- It can be categorized into system software and application software.
Option B: Firewalls
- Firewalls are software programs or applications that monitor and control incoming and outgoing network traffic based on predetermined security rules.
- They act as a barrier between a trusted internal network and an untrusted external network, providing protection against unauthorized access and threats.
- Firewalls can be installed on individual computers or network devices such as routers or dedicated firewall appliances.
Explanation:
- Among the given options, firewalls are the software that is used to protect computer networks from unauthorized access and threats.
- Routers (Option A), gateways (Option C), and modems (Option D) are hardware devices that are used for network connectivity and data transmission, but they do not fall under the category of software.
- Firewalls, on the other hand, are software programs that are installed on computers or network devices to provide security and control over network traffic.
- Therefore, the correct answer is Option B: Firewalls.
