1. Why do we perceive chlorophyll as green?

• A. It absorbs yellow and blue light.
• B. It primarily absorbs green light.
• C. It fails to absorb green light.
• D. It primarily absorbs red light.

Correct answer: A

Rationale: Chlorophyll appears green to us because it primarily absorbs yellow and blue light while reflecting green light. The wavelengths of yellow and blue light are absorbed by chlorophyll for photosynthesis, which results in the green color we perceive. Choice B is incorrect because chlorophyll absorbs yellow and blue light, not green light. Choice C is incorrect because chlorophyll does absorb green light, but it also absorbs other wavelengths, primarily yellow and blue. Choice D is incorrect because chlorophyll primarily absorbs yellow and blue light, not red light.

2. What is the best meaning of Pernicious?

• A. Harmless
• B. Destructive
• C. Helpful
• D. Harmful

Correct answer: B

Rationale: The correct answer is B, 'Destructive.' Pernicious is an adjective that describes something that is extremely harmful or destructive. Choice A, 'Harmless,' is the opposite of pernicious. Choice C, 'Helpful,' is a positive term and does not align with the meaning of pernicious. Choice D, 'Harmful,' is a similar term to pernicious but lacks the emphasis on the severe and damaging nature of the word.

3. What is implied by this paragraph?

• A. Overeating and alcohol abuse can lead to serious health issues.
• B. We should implement stricter laws to prevent alcohol abuse.
• C. Emotional eating is a major health concern.
• D. Consuming food and drinks in moderation is crucial.

Correct answer: A

Rationale: The paragraph implies that overeating and alcohol abuse can lead to serious physical and mental health problems. It highlights the strain on the heart, risk of diabetes, and shortened lifespan due to overeating. It also mentions the negative consequences of alcohol abuse, such as alcoholism, drunk driving leading to accidents, and spousal/child abuse. While emotional eating is mentioned, the main focus is on the health risks of overeating and alcohol abuse. Therefore, choice A is the correct answer as it captures the essence of the paragraph's message.

4. How many milliliters are in 5 liters?

• A. 5000 milliliters
• B. 50 milliliters
• C. 500 milliliters
• D. 0.5 milliliters

Correct answer: A

Rationale: To convert liters to milliliters, remember there are 1,000 milliliters in a liter. So, to find how many milliliters are in 5 liters, you multiply 5 (liters) by 1,000 (milliliters per liter), which equals 5,000 milliliters. Choice A is correct as it converts 5 liters to milliliters accurately. Choice B, 50 milliliters, is incorrect as it mistakenly converts liters to milliliters by a factor of 100 instead of 1,000. Choice C, 500 milliliters, is incorrect as it also wrongly converts liters to milliliters by a factor of 10 instead of 1,000. Choice D, 0.5 milliliters, is incorrect as it inaccurately converts 5 liters to 0.5 milliliters, which is not correct.

5. What charge do Group IIA elements typically have?

• A. 1
• B. +2
• C. -3
• D. 0

Correct answer: B

Rationale: Group IIA elements belong to the alkaline earth metals group in the periodic table. These elements typically have a charge of +2 because they readily lose two electrons to achieve a stable electron configuration. Therefore, the correct answer is B - +2. Choice A (1) is incorrect because Group IIA elements lose two electrons, not one. Choice C (-3) is incorrect because Group IIA elements do not gain electrons to have a negative charge. Choice D (0) is incorrect because Group IIA elements do lose electrons and have a positive charge, not a neutral charge.
