1. What is 0.2 rounded to the nearest tenth?

• A. 0.1
• B. 0.2
• C. 0.3
• D. 0.25

Correct answer: B

Rationale: The decimal 0.2 is already at the nearest tenth, so it does not need to be rounded. Rounding to the nearest tenth means keeping one decimal place, which is already the case with 0.2. Therefore, the correct answer is 0.2, as it is already at the specified rounding point. Choices A, C, and D are incorrect because they represent values that are not the result of rounding 0.2 to the nearest tenth. 0.1 is rounding down, 0.3 is rounding up, and 0.25 is not the nearest tenth of 0.2.

2. Which of the following is the main organ responsible for producing antibodies?

• A. Thymus gland
• B. Spleen
• C. Bone marrow
• D. Lymph nodes

Correct answer: C

Rationale: Antibodies are proteins produced by specialized white blood cells called B lymphocytes (B cells). These B cells mature in the bone marrow, where they undergo a process of differentiation and maturation to become plasma cells that secrete antibodies. The bone marrow is the primary site for the production of B cells and antibodies in the immune system. The thymus gland is responsible for the maturation of T lymphocytes (T cells), not antibody production. The spleen and lymph nodes play roles in filtering and trapping pathogens but are not the main organs responsible for producing antibodies.

3. Which hormone, produced by the thyroid gland, plays a crucial role in regulating the body's metabolism, growth, and development?

• A. Calcitonin
• B. Parathyroid hormone (PTH)
• C. Thyroxine
• D. Insulin

Correct answer: C

Rationale: Thyroxine, also known as T4, is a hormone produced by the thyroid gland that plays a crucial role in regulating the body's metabolism, growth, and development. It helps control the rate at which the body uses energy, affects protein synthesis, and influences the body's sensitivity to other hormones. Calcitonin (A) is another hormone produced by the thyroid gland, but its primary function is to regulate calcium levels in the blood. Parathyroid hormone (PTH) (B) is produced by the parathyroid glands and is involved in regulating calcium and phosphorus levels in the body. Insulin (D) is a hormone produced by the pancreas that helps regulate blood sugar levels.

4. Therefore, because, and accordingly are examples of which type of signal words?

• A. Emphasis words
• B. Compare/contrast words
• C. Cause-and-effect words
• D. Temporal sequencing words

Correct answer: C

Rationale: The correct answer is C. 'Therefore,' 'because,' and 'accordingly' are examples of cause-and-effect signal words. These words indicate a relationship between actions or events where one causes or results in another. Choice A, 'Emphasis words,' is incorrect as the given signal words do not emphasize a point but rather show cause and effect. Choice B, 'Compare/contrast words,' is incorrect as these signal words do not indicate a comparison or contrast between two ideas. Choice D, 'Temporal sequencing words,' is incorrect as the signal words provided do not specifically denote a sequence of events over time, but rather a cause-and-effect relationship.

5. What is the definition of the word 'antediluvian' in the sentence: 'Ermengarde loved spending time with her great-aunt, but she occasionally had to roll her eyes at what she considered to be Aunt Fredericka's antediluvian views about dating and relationships'?

• A. outdated
• B. confusing
• C. hostile
• D. Eager

Correct answer: A

Rationale: The word 'antediluvian' is often used to mean extremely old or outdated, especially in a derogatory sense. In this context, Ermengarde finds her great-aunt's views on dating and relationships to be old-fashioned or out of touch with modern ideas. 'Confusing', 'hostile', and 'Eager' do not accurately capture the meaning of 'antediluvian' in the given context, making them incorrect choices.
