1. When a person finds ________________ in a stressful situation, it helps to breathe deeply.

• A. Oneself
• B. Yourself
• C. Themselves
• D. Itself

Correct answer: A

Rationale: In this sentence, 'Oneself' is the correct reflexive pronoun to use when referring back to the singular subject 'a person.' It is important to match the reflexive pronoun with the singular noun. 'Yourself' and 'Themselves' are plural forms and do not agree with the singular subject 'a person.' 'Itself' is used for inanimate objects, not for people. Therefore, 'Oneself' is the most suitable choice in this context.

2. Three students measured the mass of a product of combustion. They recorded measurements of 14 g, 16 g, and 17 g. If the known mass of the product is 30 g, how would you describe the students’ measurements?

• A. Accurate
• B. Precise
• C. Both accurate and precise
• D. Neither accurate nor precise

Correct answer: B

Rationale: The students' measurements are precise because they are consistently close to each other. However, they are not accurate because all the measurements deviate from the known mass of the product (30 g). Accuracy refers to how close a measurement is to the true or accepted value, while precision refers to the level of agreement among repeated measurements. Since the students' measurements are consistent but do not align with the true value, they can be considered precise but not accurate. Choice A is incorrect because accuracy relates to the proximity of the measurements to the true value, which is not the case here. Choice C is incorrect because although the measurements are precise, they are not accurate. Choice D is incorrect because the measurements are precise as they show good agreement with each other, even though they are not accurate.

3. What is the meaning of the word 'composed' in the first paragraph?

• A. To consist of
• B. To be uniquely discovered
• C. To be set apart
• D. To be surprised

Correct answer: A

Rationale: In the context provided, 'composed' means to consist of. The paragraph explains that a drop of water is composed of an oxygen atom and two hydrogen atoms. Therefore, the correct answer is A. Choice B, 'To be uniquely discovered,' is incorrect as it does not relate to the composition of a drop of water. Choice C, 'To be set apart,' and Choice D, 'To be surprised,' are also incorrect as they do not convey the meaning of 'composed' as it is used in this paragraph.

4. How might vitamin D deficiency present?

• A. As bleeding gums
• B. As swollen extremities
• C. As red patches
• D. As crooked bones

Correct answer: D

Rationale: Vitamin D deficiency can present as crooked bones in children due to a condition called rickets. This is because vitamin D plays a crucial role in calcium absorption and bone health. Inadequate levels of vitamin D can lead to soft and weak bones, resulting in skeletal deformities such as bow legs or knock knees. Choices A, B, and C are incorrect as bleeding gums are more commonly associated with vitamin C deficiency (scurvy), swollen extremities could be a sign of various conditions like edema, and red patches are not typically a direct manifestation of vitamin D deficiency.

5. What is the meaning of the word respite as used in the first paragraph?

• A. Relief
• B. Treatment
• C. Guardian
• D. Specialist

Correct answer: A

Rationale: In this context, 'respite' refers to relief, providing caregivers with temporary rest or a break from their caregiving duties. The word 'respite' is associated with giving caregivers a brief period of relief, not with treatment, guardianship, or specialization. The extract mentions 'respite services' along with caregiver services, indicating that respite is a form of support or relief for caregivers.
