DSSSB AE Civil Tier 1 Mock Test - 9 - Question 2

Select the incorrect match in terms of correct waste management practices.

Detailed Solution for DSSSB AE Civil Tier 1 Mock Test - 9 - Question 2
  • Waste is unusable material. Waste comes in many forms.
  • Waste can be categorized as:
    • solid waste (vegetable peels, trash cans and other such municipal waste),
    • liquid waste (water discharge from industries, harmful runoff from fields etc),
    • and gaseous waste (harmful gases released from industries).

Key Points

Solid waste management is one important challenge of urban bodies. It can be achieved by following the 5 R's of waste management which are:

Refuse:

  • Refuse the usage of non-biodegradable products as much as possible.
  • Example: Refuse using plastic bags and using jute bags or cloth bags.

Reduce: 

  • If users cannot be refused completely, reduce the amount of consumption.
  • Example: Reducing the use of single-use plastics.

Reuse:

  • As much as possible try to use a substance for as long as and in as many ways as possible.
  • Example: Reuse wrapping paper, plastic bags, boxes.

Repurpose:

  • For every item that can't be refused, reduced, or reused, try repurposing it.
  • Example: try using wasted printer paper for scrap paper, cardboard boxes for storing supplies, binder clips to hold power cords

Recycle:  

  • Recycling is the most environmentally friendly waste disposal method, which means collecting waste and produce a new product from it.
  • Example: recycling of glass can be made to produce new glass jars and bottles or tiles.

Important Points

Plastic bags:

  • A plastic bag should be avoided because it is harmful to the environment and is difficult to degrade.
  • If one cannot avoid the use of plastic bags they must reuse, repurpose or recycle plastic bags.

Thus, the incorrect match is Plastic bags: Landfill

Additional Information

Composting:

  • Due to a lack of adequate space for landfills, biodegradable yard waste is allowed to decompose in a medium designed for the purpose.
  • Only biodegradable waste materials are used in composting. Example: kitchen waste
  • Good quality environmentally friendly manure is formed from the compost and can be used for agricultural purposes.
  • It is the only sustainable means of waste disposal.

Landfill:

  • Landfill refers to the disposal of waste material by burying it.
  • It is an extended storage area for non-biodegradable waste.
  • Landfills may lead to contamination from the waste entering the area surrounding by soil and water and it also causes odour and pests.

DSSSB AE Civil Tier 1 Mock Test - 9 - Question 3

What is meant by the term ‘constituency’?

Detailed Solution for DSSSB AE Civil Tier 1 Mock Test - 9 - Question 3
What is meant by the term 'constituency'?
A constituency refers to a specific area or region from where voters elect a representative to the Lok Sabha or Vidhan Sabha. It is an essential concept in the democratic electoral system. Here are the key points to understand about constituencies:
1. Definition: A constituency is a geographically defined area that represents a specific group of voters who have the right to elect a representative to a legislative body.
2. Representation: Constituencies ensure that every region or area is represented in the legislative body. Each constituency has its own representative who acts as a voice for the concerns and interests of the people in that particular area.
3. Electoral Process: During elections, voters from a constituency cast their votes to elect a candidate who will represent their interests and concerns. The candidate who receives the highest number of votes becomes the elected representative for that constituency.
4. Delimitation: Constituencies are often delimited or redrawn periodically to ensure fair representation based on population changes. This process is carried out by an independent authority to maintain equal representation among constituencies.
5. Lok Sabha and Vidhan Sabha: In India, constituencies are primarily associated with the Lok Sabha (the lower house of Parliament) and Vidhan Sabha (the state legislative assembly). Each state is divided into different constituencies, and voters from each constituency elect their representatives to these bodies.
In conclusion, a constituency is a specific area from where voters elect their representatives to the Lok Sabha or Vidhan Sabha. It ensures fair representation and gives people the opportunity to choose their leaders based on their concerns and interests.

DSSSB AE Civil Tier 1 Mock Test - 9 - Question 8
If x + 1/x = 25, find the value of x – 1/x.
Detailed Solution for DSSSB AE Civil Tier 1 Mock Test - 9 - Question 8

Given:

x + 1/x = 25

Concept Used:  

If x + 1/x = p then, x – 1/x = √(p2 – 4)

Calculation:

It is given that x + 1/x = 25

 We know that if x + 1/x = p then, x – 1/x = √(p2 – 4)

⇒ x – 1/x = √(252 – 4)

⇒ x – 1/x = √(625 – 4)

⇒ x – 1/x = √621

∴ value of x – 1/x is √621.

DSSSB AE Civil Tier 1 Mock Test - 9 - Question 13

Direction: Read the following passages carefully and answer the question that follows.
"Cloning is an advanced technological invention for producing a genetic twin of a living thing, an organism that starts life with the same genes as its parents. In mammals, DNA is taken from an adult animal and then it is inserted into an egg cell from another animal. This egg then divides into an embryo. The embryo is then transplanted into a surrogate mother and grown to term. This process has worked in animals like cows, sheep, goats, mice, pigs, rats, cat, monkeys, and horses." The opponents of human cloning say that an embryo at any stage of development is a human life. worthy of protection and any kind of research that entails destroying an embryo is immoral, unethical, no matter how worthy the intent may be. It involves using human beings as means; it turns human life into a commodity and fosters a culture of dehumanization.

Q. What does a 'surrogate mother' mean?

Here the expression surrogate has been used as an adjective meaning replacing someone else (human beings or animals) or used instead of somethings else. In this way option 'd' clears the meaning.

DSSSB AE Civil Tier 1 Mock Test - 9 - Question 14

Direct shear test can be conducted for :

Detailed Solution for DSSSB AE Civil Tier 1 Mock Test - 9 - Question 14
1. Unconsolidated Undrained Test (UU)

Drainage is not permitted throughout the test. In the case of direct shear test drainage is not permitted during the application of both normal stress and shear stress. In the case of triaxial compression test drainage is not permitted during the application of both cell pressure and deviator stress. Since the test is conducted fast allowing no time for either consolidation of sample initially or dissipation of pore pressure in later stage, the test is also called quick test.

2. Consolidated Undrained Test (CU)

In this type of shear test the soil specimen is allowed to consolidate fully under initially applied stress and then sheared quickly without allowing dissipation of pore pressure. In the case of direct shear test the specimen is allowed to consolidate fully under applied normal stress and then sheared at high rate of strain to prevent dissipation of pore pressure during shearing. In the case of triaxial compression test the specimen is allowed to consolidate fully under the applied cell pressure and then the pore water outlet is closed and the specimen is subjected to increasing deviator stress at higher rate of strain.

3. Consolidated Drained Test (CD)

In this type of shear test drainage is allowed throughout the test. The specimen is allowed to consolidate fully under the applied initial stress and then sheared at low rate of strain giving sufficient time for the pore water to drain out at all stages. The test may continue for several hours to several days.

Hence, the correct option is (D)
