A. Dispersed.
B. Incensed.
C. Painstaking.
D. Demanding.

Correct answer: C

Rationale: In the context of sickle-cell anemia, diligent means painstaking, indicating the careful and thorough approach required to manage the disease. The passage highlights the challenges of managing the symptoms of sickle-cell anemia and the need for meticulous and conscientious care. Choices A, B, and D are incorrect. 'Dispersed' and 'Incensed' do not align with the meaning of diligent in this context. 'Demanding' does not capture the essence of the careful and thorough care needed to manage the disease.

A. Condensation fails to happen when water vapor cools and changes back into droplets of liquid
B. Evaporation happens when water changes into gas
C. The water cycle does not involve precipitation
D. Water evaporates from oceans and rivers

Correct answer: C

Rationale: Choice C, 'The water cycle does not involve precipitation,' is not a detail from the passage. The passage clearly states that precipitation, such as rain, snow, sleet, or hail, is a crucial part of the water cycle. On the other hand, choices A, B, and D are all supported by the passage. Condensation occurs when water vapor cools, evaporation occurs when water changes into gas, and water evaporates from oceans and rivers are all mentioned in the text.

3. What is the meaning of the word supplementation as used in the second paragraph?

Correct answer: A

Rationale: The term "supplementation" refers to the addition of nutrients to the diet.

This reflects the understanding that seniors may not get sufficient nutrition solely from their regular meals, supporting option A.

Correct answer: D

Rationale: The correct answer is D because the passage specifically states that at the nanoscale, unique properties of materials emerge, which is a key benefit of nanotechnology. Choice A talks about what scientists can do but does not directly describe the benefits mentioned in the passage. Choice B is the definition of nanotechnology and not a specific benefit. Choice C mentions the use of different colors in medical tests, which is a specific application rather than a general benefit of nanotechnology.
