C Correct answer
Explanation

The sentence structure 'disadvantages are also ___ with it' requires a verb that connects disadvantages to air conditioning. Associated means connected or related to something, which fits perfectly - disadvantages are connected to air conditioning alongside its benefits. 'Attached' is less natural in this context, and other options don't fit the preposition 'with' or the meaning.

D Correct answer
Explanation

The phrase 'scientists are ___ on' requires a verb that pairs naturally with the preposition 'on'. Working on something means actively engaged in that activity or task, which fits perfectly. Scientists are actively engaged in developing environmentally friendly products. Other options like 'developing' or 'researching' would typically use different prepositions.

  1. helps

  2. impacts

  3. effects

  4. distinguishes

  5. improves
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The passage describes negative environmental effects of air conditioning through fluorocarbon refrigerants. The phrase 'main ways in which air-conditioning ___ the environment' requires a neutral term that can describe both positive and negative effects. Impacts means affects or influences, which is appropriate here since the passage discusses how air conditioning affects the environment negatively through global warming and ozone depletion.

Multiple choice

Which of the following factors is mainly responsible for the rise in temperature of the atmosphere?

  1. Increase in the atmospheric density

  2. Increase in the usage of renewable energy

  3. Increase in the amount of carbon dioxide

  4. Decrease in the atmospheric humidity
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Carbon dioxide is the primary greenhouse gas responsible for atmospheric warming through the greenhouse effect. Increased CO₂ from burning fossil fuels, deforestation, and industrial activities traps more heat in the atmosphere, causing global temperatures to rise. Other factors listed are either unrelated or would decrease warming.

Multiple choice

When we open a container of perfume, the smell of the perfume spreads in the room within a short period due to

  1. sublimation

  2. evaporation

  3. diffusion

  4. None of these
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The smell of the perfume spreads in the room within a short period due to diffusion. Diffusion is the net movement of molecules or atoms from a region of high concentration (or high chemical potential) to a region of low concentration (or low chemical potential). The rate of diffusion of liquids is higher than that of solids. This is due to the fact that in the liquid state, particles move freely and have greater space between each other as compared to particles in the solid state.

Multiple choice

A man feels unpleasant due to excessive humidity and warmth. The reason is

  1. more sweating

  2. less sweating

  3. sweat does not evaporate due to humidity

  4. sweat is not formed due to humidity
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

High humidity prevents sweat from evaporating, which is the body's primary cooling mechanism. When sweat doesn't evaporate, the body cannot cool effectively, causing discomfort. The body still produces sweat (option D is wrong), but it accumulates on the skin instead of evaporating. Less sweating (option B) would not cause discomfort.

Multiple choice

Which of the following statements is incorrect for environment?

  1. It includes only physical factors of surroundings.

  2. Water and air are the physical factors of an environment.

  3. Gas, light and temperature are its physical factors.

  4. It is a natural habitat for some animals.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Statement A is incorrect because the environment includes BOTH physical (abiotic) factors AND living (biotic) organisms. Options B, C, and D correctly identify physical factors and acknowledge that environment provides habitat for animals.

Multiple choice

Amount of moisture in the air is called ______

  1. Humidity

  2. Climate

  3. Rancidity

  4. Rain
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Humidity specifically refers to the amount of water vapor present in the air. Climate is long-term weather patterns, rancidity is fat oxidation, and rain is precipitation. Humidity is the precise meteorological term for moisture content in the atmosphere.
