✍️ Sample CAEC Questions & Answers

1. What is the precautionary principle in science and technology policy?
✓ The principle that when an action or technology poses a potential risk to people or the environment, precautionary measures should be taken even before scientific certainty is established

The precautionary principle states that lack of full scientific certainty should not be used as a reason to postpone protective action when there is evidence of potential harm.

2. What is the greenhouse effect, and how does human activity contribute to it?
✓ The greenhouse effect is a natural process where atmospheric gases trap heat; human activity enhances it by increasing greenhouse gas concentrations through burning fossil fuels

The greenhouse effect is natural, but human activities — particularly burning fossil fuels — release extra CO₂ and methane, intensifying warming beyond natural levels.

3. What is the role of DNA in living organisms?
✓ To store and transmit genetic information that directs the growth and function of cells

DNA (deoxyribonucleic acid) carries the genetic instructions used in the growth, development, functioning, and reproduction of all known living organisms.

4. What is the mean of the data set 4, 7, 9, 12, 13?
✓ 9

The sum is 45 and there are 5 values, so the mean is 45 ÷ 5 = 9.

5. Which of the following is an example of a logical fallacy that weakens a persuasive argument?
✓ Claiming that something must be true because many people believe it (appeal to popularity)

An appeal to popularity (ad populum) is a logical fallacy — something is not necessarily true just because many people believe it.

6. Which of the following correctly describes the primary function of mitochondria within a eukaryotic cell?
✓ To generate most of the cell's supply of adenosine triphosphate (ATP) through cellular respiration.

The mitochondrion is known as the 'powerhouse' of the cell. Its main function is to perform cellular respiration, a process that breaks down nutrients and turns them into adenosine triphosphate (ATP), the main energy-carrying molecule used to power the cell's metabolic activities.
