Questions and Answers
  • 1. 

    The Pollution Standard Index (PSI) scale has span from

    • A.

      0-200

    • B.

      0-300

    • C.

      0-400

    • D.

      0-500

    Correct Answer
    D. 0-500
    Explanation
    The Pollution Standard Index (PSI) scale has a span from 0-500. This indicates that the scale measures pollution levels ranging from 0 (no pollution) to 500 (extremely hazardous pollution). The higher the PSI value, the worse the air quality and the greater the health risks associated with it. This wider range allows for a more comprehensive assessment of pollution levels and enables authorities to take appropriate measures to mitigate the impacts of high pollution levels.

    The major contributor of Carbon monoxide is

    • A.

      Motor vehicle

    • B.

      Industrial processes

    • C.

      Stationary fuel combustion

    • D.

      None of the above

    Correct Answer
    A. Motor vehicle
    Explanation
    Motor vehicles are a major contributor of carbon monoxide because they emit this harmful gas as a byproduct of combustion. The combustion of gasoline or diesel in engines produces carbon monoxide, which is released into the atmosphere through vehicle exhausts. This gas is toxic and can have detrimental effects on human health and the environment. Industrial processes and stationary fuel combustion can also contribute to carbon monoxide emissions, but motor vehicles are a significant source due to the large number of vehicles on the roads globally.

    The function of automobile catalytic converter is to control emissions of 

    • A.

      Carbon dioxide and hydrogen

    • B.

      Carbon monoxide and hydrogen

    • C.

      Carbon monoxide and carbon dioxide

    • D.

      Carbon monoxide and nitrogen dioxide

    Correct Answer
    B. Carbon monoxide and hydrogen
    Explanation
    The function of an automobile catalytic converter is to control emissions of carbon monoxide and hydrogen. This device helps to convert harmful gases, such as carbon monoxide and unburned hydrocarbons, into less harmful substances, like carbon dioxide and water vapor. By doing so, it reduces the amount of pollutants released into the atmosphere, contributing to cleaner air and reducing the negative impact on the environment.

    What’s the top source of renewable energy in the world?

    • A.

      Solar

    • B.

      Bio-mass

    • C.

      Hydropower

    • D.

      Wind

    Correct Answer
    B. Bio-mass
    Explanation
    Bio-mass is the top source of renewable energy in the world. This is because bio-mass refers to organic matter such as plants, agricultural waste, and wood, which can be converted into energy through various processes like combustion or fermentation. Bio-mass energy is widely used for heating, electricity generation, and transportation fuel. It is considered a renewable energy source because plants and crops can be continuously grown and harvested to produce bio-mass fuel. Additionally, bio-mass energy helps reduce greenhouse gas emissions and dependence on fossil fuels, making it an environmentally friendly and sustainable energy option.

    Rate this question:

  • 5. 

    ____ unit/s energy is reached to consumption level if ____ unit/s are generated in Power Plant.

    • A.

      2,4

    • B.

      3,9

    • C.

      2,5

    • D.

      1,1

    Correct Answer
    B. 3,9
    Explanation
    If 3 units of energy are generated in a power plant, it means that 9 units of energy are reached to the consumption level. This suggests that there is a conversion or efficiency factor at play, where the energy generated in the power plant is multiplied by a factor of 3 to reach the consumption level.

  • 6. 

    Who said “Earth provides enough to satisfy every man’s need, but not every man’s greed”. 

    • A.

      Subash Chandra Bose

    • B.

      Madhusudan Das

    • C.

      Mahatma Gandhi

    • D.

      Mother Teresa

    Correct Answer
    C. Mahatma Gandhi
    Explanation
    Mahatma Gandhi said, "Earth provides enough to satisfy every man's need, but not every man's greed." This quote reflects Gandhi's belief in the importance of living in harmony with nature and practicing moderation. He emphasized that the Earth's resources are sufficient to fulfill everyone's basic needs, but excessive greed and consumption can lead to inequality and environmental degradation. Gandhi advocated for simple living and self-sufficiency, promoting a sustainable and equitable society.

    According to Amory Lovins, the easiest, fastest, and cheapest way to get more energy with the least environmental impact is to 

    • A.

      Improve photovoltaics

    • B.

      Develop wind power

    • C.

      Initiate the second wave of nuclear power plants in the United States

    • D.

      Eliminate energy waste

    Correct Answer
    D. Eliminate energy waste
    Explanation
    Amory Lovins suggests that the easiest, fastest, and cheapest way to get more energy with the least environmental impact is to eliminate energy waste. This means focusing on improving energy efficiency and reducing unnecessary energy consumption. By doing so, we can maximize the use of existing energy resources and minimize the need for additional energy production, such as developing new technologies like photovoltaics or wind power, or initiating new nuclear power plants. Eliminating energy waste is a more practical and sustainable solution that can be implemented immediately to address the energy challenge.

    Click the most frequently overcharged gadget 

    • A.

      Mobile Phones

    • B.

      Electric toothbrush

    • C.

      Laptops

    • D.

      IPods and MP3 players

    Correct Answer
    A. Mobile Phones
    Explanation
    Mobile phones are the most frequently overcharged gadget because they are used extensively throughout the day and often require frequent charging. People tend to keep their phones connected to chargers even when the battery is already full, which can lead to overcharging. Additionally, mobile phones are more prone to overcharging compared to other gadgets due to their smaller battery size and the fact that they are often left charging overnight or for extended periods of time.

      Global warming

    • B.

      AIDS

    • C.

      Food Security

    • D.

      Solar energy

    Correct Answer
    A. Global warming
    Explanation
    The Kyoto Protocol is an international agreement that aims to address the issue of global warming. It sets binding targets for countries to reduce their greenhouse gas emissions in order to mitigate climate change. The protocol establishes mechanisms for countries to cooperate and implement measures to reduce emissions, such as promoting the use of renewable energy sources and improving energy efficiency. Therefore, the correct answer is global warming.

  • 10. 

    Which among the following is most energy efficient?

    • A.

      Incandescent bulb

    • B.

      Fluorescent tube light

    • C.

      Compact fluorescent lamp

    • D.

      All are equally efficient

    Correct Answer
    C. Compact fluorescent lamp
    Explanation
    The compact fluorescent lamp is the most energy efficient among the given options. This is because it uses less energy to produce the same amount of light compared to the other options. Incandescent bulbs are known for their high energy consumption and low efficiency as they produce more heat than light. Fluorescent tube lights are more efficient than incandescent bulbs but still less efficient than compact fluorescent lamps. Compact fluorescent lamps use a combination of gas and electricity to produce light, making them more energy efficient and longer-lasting.

    The Threshold (or Upper Limit) for what is considered a hazardous noise level is:

    • A.

      80 dB

    • B.

      85 dB

    • C.

      90 dB

    • D.

      95 dB

    Correct Answer
    B. 85 dB
    Explanation
    The correct answer is 85 dB. The threshold for what is considered a hazardous noise level is typically set at 85 dB. This is because prolonged exposure to noise levels above 85 dB can cause damage to the ears and lead to hearing loss. It is important to take measures to protect oneself from excessive noise levels, such as wearing ear protection in loud environments.
