1. What does concave mean?

• A. Rounded inward
• B. Rounded outward
• C. Straight
• D. Flat

Correct answer: A

Rationale: Concave means rounded inward. When something is concave, it curves inwards like the interior of a bowl. Choice B, 'Rounded outward,' is incorrect as this describes a convex shape, not concave. Choice C, 'Straight,' is incorrect as concave refers to a curved shape, not a straight one. Choice D, 'Flat,' is also incorrect as it does not describe the inward curve characteristic of concave shapes.

2. Which statement from the passage on Voice is a fact rather than an opinion?

• A. One of the worst voice qualities is harshness.
• B. Harsh voice qualities come from tension in the throat.
• C. Your voice will sound unpleasant if it is shrill or grating.
• D. Because tension occurs in higher-pitched voices, women tend to have shriller voices than men.

Correct answer: B

Rationale: The correct answer is B. The fact that harsh voice qualities come from tension in the throat is a verifiable statement based on a scientific explanation provided in the passage. This statement is not subject to personal interpretation or judgment. Choice A is an opinion as it categorizes harshness as one of the worst voice qualities, which is subjective. Choice C is also an opinion as it describes how a voice will sound based on subjective terms like 'unpleasant.' Choice D is an opinion as it makes a generalized statement linking higher-pitched voices with shriller voices in women, which can vary widely among individuals.

3. Which muscle in the shoulder is the deltoid?

• A. dendrite
• B. delphic
• C. deltoid
• D. dentate

Correct answer: C

Rationale: The deltoid muscle is located in the shoulder area. It is a rounded, triangular muscle that covers the shoulder joint and is responsible for lifting the arm and providing shoulder stability. The other options provided, dendrite, delphic, and dentate, are not muscles in the shoulder region.

4. To the nearest whole number, what is the mass of one mole of hydrogen iodide?

• A. 2 g/mol
• B. 58 g/mol
• C. 87 g/mol
• D. 128 g/mol

Correct answer: C

Rationale: The molar mass of hydrogen iodide (HI) is the sum of the atomic masses of its constituent elements. Hydrogen (H) has a molar mass of approximately 1 g/mol, and iodine (I) has a molar mass of about 127 g/mol. Thus, the molar mass of hydrogen iodide (HI) is approximately 1 + 127 = 128 g/mol. Rounding to the nearest whole number, the molar mass of hydrogen iodide is 128 g/mol, which is closest to choice C. Choice A (2 g/mol) is too low and does not reflect the correct molar mass of hydrogen iodide. Choice B (58 g/mol) is significantly lower than the actual molar mass. Choice D (128 g/mol) matches the calculated molar mass but is not the nearest whole number as requested.

5. Choose the meaning of the word vent in the following sentence: 'A tube is used to vent the gases to the outside.'

• A. Block
• B. Trade
• C. Emit
• D. Inhale

Correct answer: C

Rationale: In this sentence, the word 'vent' means to allow the gases to escape or be emitted to the outside. 'Block' is incorrect because it means to obstruct or close off. 'Trade' is incorrect as it refers to the exchange of goods or services. 'Inhale' is incorrect as it means to breathe in, which is the opposite of venting gases out.
