TEAS 7 English Practice Test

1. In the words proactive, progress, and projecting, pro- is a(n) _______ that means _______.

Correct answer: B

Rationale: In the words proactive, progress, and projecting, 'pro-' is a prefix meaning 'before, forward, or front.' This prefix denotes something happening before or moving forward, as seen in 'progress' and 'projecting,' where it signifies moving ahead or progressing. Therefore, the correct answer is B. Choices A, C, and D are incorrect because 'pro-' is not a suffix, affix, or prefix that means 'good, on top of, or over,' 'after, behind, or in back of,' or 'against, under, or below' respectively. The key is to recognize the meaning of the prefix 'pro-' in the given words and associate it with concepts related to being before or moving forward.

2. How many milligrams are in 2 grams?

Correct answer: B

Rationale: To convert grams to milligrams, you need to multiply by 1,000 since there are 1,000 milligrams in a gram. Therefore, 2 grams is equal to 2,000 milligrams. Choice A (200 mg) is incorrect as it represents 0.2 grams. Choice C (20 mg) is incorrect as it represents 0.02 grams. Choice D (20,000 mg) is incorrect as it represents 20 grams.

3. Where does the digestion of food start?

Correct answer: D

Rationale: The correct answer is the mouth. Digestion begins in the mouth where mechanical breakdown occurs through chewing, and chemical breakdown begins with saliva. Enzymes in saliva start breaking down carbohydrates, initiating the digestion process. The esophagus is responsible for transporting food from the mouth to the stomach and does not play a role in the digestion process. The stomach continues the digestion process after the food leaves the mouth. The small intestine is primarily responsible for absorbing nutrients from the digested food, rather than being the initial site of digestion.

4. Solve for x: x + 5 = x - 3.

Correct answer: A

Rationale: To solve the equation x + 5 = x - 3, we aim to isolate x. By subtracting x from both sides, we get 5 = -3, which is not possible. This indicates that the equation has no solution. Therefore, the correct answer is x = -5. Choices B, C, and D are incorrect as they do not yield a valid solution when substituted back into the original equation.

5. What is the common name for the compound CH₃COOH?

Correct answer: A

Rationale: The compound CH₃COOH is commonly known as acetic acid. Acetic acid is a clear, colorless liquid with a sour taste and a pungent smell. It is a weak acid found in vinegar and is used in the production of various chemicals. Formic acid, butyric acid, and propionic acid are different organic acids with distinct chemical structures and properties, but they are not the common name for the compound CH₃COOH.
