DSSSB AE Civil Tier 1 Mock Test - 2 - Civil Engineering (CE) MCQ

Hydrological Cycle

• The process of circulation of water within the hydrosphere of Earth in different forms such as liquid, solid and gaseous states are called the Hydrological Cycle of water.
• It starts with the Evaporation of water from the surface of the water bodies and further, it includes Transpiration, Sublimation, Condensation and Precipitation.

Key Points

'Hydrological cycle' steps

• The first step of the water cycle is evaporation from water bodies means the part of the Hydrosphere.
• The second step of the water cycle is condensation, which takes place in the atmosphere.
• The third step of the water cycle is precipitation and runoff means the part of the lithosphere.
• The final step of the water cycle is in the Biosphere. 
• It is the zone where all the spheres interact and work together.
• It includes processes like water uptake and transpiration by plants.

​

Thus, in the 'Hydrological cycle' the order of the source in which they connected from each other is first Hydrosphere, second Atmosphere, third Lithosphere and fourth Biosphere.

Additional Information

Processes during a hydrological cycle:

​​Evaporation

• When waters convert from liquid to gas stage as it moves from the groundwater into the atmosphere, this phenomenon is called Evaporation.
• Mainly Solar radiation is the source of energy for evaporation. 

Transpiration

• When plant uptake of water at the roots, transport of water through plant tissues, and release of vapour by leaves is known as transpiration.

Condensation

• The Process of conversion of water vapour to liquid water droplets in the air is called Condensation.
• It is responsible for the formation of fog and clouds.

​Precipitation

• When the condensed water vapour falling to the surface of the Earth is known as Precipitation.
• It occurs in the form of rain, snow, and hail.
• It provides for the delivery of atmospheric water to the earth in the form of rain.

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 Small Industries Development Bank of India (SIDBI) has announced the launch of a pilot phase of ‘Mission 50K-EV4ECO’
The pilot scheme aims at strengthening the EV ecosystem, including uptake for two, three and four-wheelers through direct and indirect lending.

Fish was the royal emblem of Pandya Kingdom. The Pandyas were also mentioned by Megasthanese who said that then kingdom was famous for pearls.

As chalk is used to write on the blackboard similarly the Ink is used to write on the paper.

From the final arrangement, we get T faces Q.
Hence, Option C is correct.
References:
Q sits second to the right of P.
Inferences:
From the above reference, we get two different cases:
In case 1, P sits at the corner or in the middle of the side of the table.

References:
R is not an immediate neighbor of P.
R faces inside.
R sits third to the left of W.
Inferences:
From the above references, we get different cases for R, in case 1(a) in which R faces P and in case 1(b) R faces Q.

References:
T sits third to the left of U.
V sits second to the left of U.
Inferences:
So, from this case 1(b) and case 2 will be eliminated as there is no possible place for V in these cases after placing U and T. Hence, we get our final arrangement in which S sits on the immediate left of P and V sits on the immediate right of R.
Final arrangement:

As short form of 'Mountain' is 'Hill' similarly 'Tank' is short form of 'River'.

Esteemed means regarded with respect, honored, prestigious

The esteemed panel discussed crucial issues on a televised debate

The esteemed judge ruled in the favor of convict due to lack of evidence

The correct preposition to use in the given sentence is "between." Let's examine the options and understand why "between" is the best choice.

A: between
- This is the correct choice because it indicates that Mary is sitting in the middle of John and Jill, with one person on each side.
B: on
- This would imply that Mary is sitting physically on top of John and Jill, which is incorrect and not suitable in this context.
C: in front of
- This would indicate that Mary is sitting ahead of John and Jill, which doesn't make sense in this context as it doesn't convey the idea of Mary sitting with them.
D: over
- Similar to "on," this would imply that Mary is sitting above John and Jill, which is incorrect and not suitable in this context.
Therefore, the correct preposition to complete the sentence is "between."

The correct order will be:
A French woman → who had come to calcutta (R)→ committted suicide (P)→ by jumping from the first floor balcony of the hotel (S)→ where she had put up. (Q)

We can say that ,
The above given sentence is given in Passive Voice :-
Use structure “subject + auxiliary + past participle + by + object”
Your shoes need to be cleaned properly .
Thus , required answer will be option C .

Knack means an acquired or natural skill at doing something

Japan's auto makers have also developed a knack for creating pleasing interiors
You have a knack for crafting pithy and elemental descriptions of personalities
He was a trained aeronautical engineer, race pilot and had a knack for business

(i_c= G−1/1+e)

Where,

G= Specific gravity and e= void ratio

Hence on increasing the void ratio, the critical hydraulic gradient will decrease.

Hence the correct answer is option B.

The primary treatment of sewage involves the following steps:

• Removal of floating materials: This step helps eliminate larger debris and substances that can harm the treatment process.
• Removal of sand and grit: This process ensures that heavier particles are filtered out to prevent damage to equipment.

Both of these actions are essential for effective sewage treatment, as they prepare the sewage for further treatment stages. Therefore, Correct Answer is Option C.

Hence the correct answer is option D.

t=C+σ tanφ

Where σ = effective vertical stress

C = cohesion

φ = angle of internal friction of soil

Thin-walled cre samplers are most commonly used for the collection of undisturbed core samples in cohesive soils, silt, and sand above the water table.

(K_a=1−sin⁡θ/1+sin⁡θ)

(=tan^2⁡(45−θ/2))

Where (θ)= angle of internal friction.

Hence the correct answer is option B.

Hence the correct answer is option C.

A good building stone should possess several characteristics such as high strength (i.e., crushing strength >1000kg/cm² ) (100 Mpa)), high durability, sufficient hardness (i.e., coefficient of hardness >14 ), high resistance of wear, good fire resistance specific gravity more than 2.7, crystalline structure, high impact value (i.e., toughness index >13 ), low water absorption (i.e., Percentage absorption after 24 hours less than 0.6 ), facility for carving and dressing, weather resistance and better appearance. Generally, stones from igneous and metamorphic rocks are heavier and more durable than stones from sedimentary rocks.

Hence the correct answer is option A.
