Questions and Answers
  • 1. 

    Example for water-borne disease is _________

    • A.

      Scabies

    • B.

      Dracunculiasis

    • C.

      Trachoma

    • D.

      Typhoid

    Correct Answer
    D. Typhoid
    Explanation
    Typhoid is a water-borne disease caused by the bacterium Salmonella Typhi. It is transmitted through contaminated food and water, making it a suitable explanation for the given question.

  • 2. 

    The settled and floating materials are removed by this treatment method.

    • A.

      Primary treatment

    • B.

      Secondary treatment

    • C.

      Tertiary treatment

    • D.

      Peripheral treatment

    Correct Answer
    A. Primary treatment
    Explanation
    Primary treatment is the initial step in wastewater treatment where settled and floating materials are removed. This process involves physical methods such as screening, sedimentation, and flotation to separate solid particles and debris from the wastewater. The primary treatment helps to reduce the organic load and remove large solids, which improves the efficiency of subsequent treatment processes.

  • 3. 

    Which is a non-renewable resource?

    • A.

      Coal

    • B.

      Petroleum

    • C.

      Natural gas

    • D.

      All the above

    Correct Answer
    D. All the above
    Explanation
    Coal, petroleum, and natural gas are all examples of non-renewable resources. Non-renewable resources are finite and cannot be replenished within a human lifespan. These resources are formed over millions of years through geological processes and their extraction and consumption rates far exceed their natural replenishment rate. As a result, these resources are being depleted faster than they can be replaced. Once these resources are exhausted, they cannot be easily replaced, making them non-renewable.

    Rate this question:

  • 4. 

    ----------- is the chief component of natural gas.

    • A.

      Ethane

    • B.

      Methane

    • C.

      Propane

    • D.

      Butane

    Correct Answer
    B. Methane
    Explanation
    Methane is the chief component of natural gas. Natural gas is primarily composed of methane, with smaller amounts of other hydrocarbon gases such as ethane, propane, and butane. Methane is the main component because it is the simplest hydrocarbon, consisting of a single carbon atom bonded to four hydrogen atoms. It is highly flammable and is commonly used as a fuel for heating and cooking purposes.

  • 5. 

    Odd one out.  bio alcohol, green diesel, bio ethers, petroleum

    • A.

      Bio alcohol

    • B.

      Green diesel

    • C.

      Bio ethers

    • D.

      Petroleum

    Correct Answer
    D. Petroleum
    Explanation
    The odd one out in this group is petroleum. The other three options (bio alcohol, green diesel, bio ethers) are all forms of renewable or alternative fuels, while petroleum is a fossil fuel.

    Rate this question:

  • 6. 

    Odd one out.  cholera, typhoid, scabies, dysentery

    • A.

      Cholera

    • B.

      Typhoid

    • C.

      Scabies

    • D.

      Dysentery

    Correct Answer
    C. Scabies
    Explanation
    The odd one out in this list is scabies because it is the only condition that is caused by a parasitic mite infestation, while the other three options are all infectious diseases caused by bacteria (cholera and typhoid) or a parasite (dysentery).

    Rate this question:

  • 7. 

    Pick out the suitable appliances to conserve the electric energy. Florescent bulbs, copper choke, electric water heater, tungsten bulbs

    • A.

      Florescent bulbs

    • B.

      Copper choke

    • C.

      Electric water heater

    • D.

      Tungsten bulbs

    Correct Answer
    A. Florescent bulbs
    Explanation
    Fluorescent bulbs are a suitable appliance to conserve electric energy because they are more energy-efficient compared to tungsten bulbs. Fluorescent bulbs use less electricity to produce the same amount of light as tungsten bulbs, resulting in lower energy consumption and reduced electricity bills. Additionally, fluorescent bulbs have a longer lifespan, reducing the frequency of replacements and further saving energy. Copper choke and electric water heaters are not directly related to conserving electric energy, while tungsten bulbs are known for their high energy consumption.
