1. What units of measurement would a triple beam balance show?

• A. Liters
• B. Grams
• C. Meters
• D. Gallons

Correct answer: B

Rationale: A triple beam balance is used to measure mass, typically in grams. Liters, meters, and gallons are units of volume, length, and capacity, respectively, not typically measured using a triple beam balance. Therefore, the correct answer is grams. Choice A, Liters, is a unit of volume. Choice C, Meters, is a unit of length. Choice D, Gallons, is a unit of capacity. These units are not typically measured using a triple beam balance.

2. Which of the following sentences uses second person point of view?

• A. I don't want to make plans for the weekend before I see my work schedule.
• B. She had to miss the last three yoga classes due to illness.
• C. Pluto is no longer considered a planet because it is not gravitationally dominant.
• D. Be sure to turn off all of the lights before locking up for the night.

Correct answer: D

Rationale: The correct answer is D. This sentence uses the second person point of view by directly addressing the reader or listener with the phrase 'Be sure to.' It is instructing or advising someone on what action to take, making it a clear example of second person point of view. Choices A, B, and C all use first person (I) or third person (she, Pluto), which do not involve direct interaction with the reader or listener, unlike the second person point of view present in choice D.

3. In nuclear physics, the term 'barn' is a unit commonly used to quantify:

• A. Energy
• B. Radioactivity
• C. Nuclear cross-section
• D. Half-life

Correct answer: C

Rationale: In nuclear physics, the term 'barn' is a unit used to quantify nuclear cross-section. Nuclear cross-section is a measure of the probability of a nuclear reaction occurring when an atomic nucleus interacts with a particle or another nucleus. The barn is a unit of area equal to 10^-28 square meters; it is commonly used to describe the cross-sectional area of atomic nuclei for nuclear reactions. Choice A, 'Energy,' is incorrect because a barn is not a unit for measuring energy; it is a unit of area. Choice B, 'Radioactivity,' is incorrect as radioactivity is typically measured in units like becquerels. Choice D, 'Half-life,' is also incorrect as half-life is a measure of the time it takes for half of a substance to decay, not related to the concept of a barn as a unit of nuclear cross-section.

4. Convert 345,000 millimeters to centimeters (cm).

• A. 34,500 cm
• B. 3,450 cm
• C. 345,000 cm
• D. 345,000,000 cm

Correct answer: B

Rationale: To convert millimeters to centimeters, you need to divide by 10 since there are 10 millimeters in 1 centimeter. Therefore, 345,000 mm ÷ 10 = 34,500 cm. Choice A is incorrect because it is a factor of 10 higher than the correct answer. Choice C is incorrect because it represents the original quantity in centimeters, not the converted value. Choice D is incorrect as it erroneously multiplies the millimeters by 1,000 instead of dividing by 10 to convert to centimeters.

5. What is the name of the condition characterized by swelling caused by a buildup of lymph fluid?

• A. Anemia
• B. Edema
• C. Hypertension
• D. Diabetes

Correct answer: B

Rationale: Edema is the condition characterized by swelling caused by a buildup of lymph fluid. It occurs when excess fluid is trapped in the body's tissues. Anemia (A) is a condition characterized by a lack of healthy red blood cells, leading to a reduced ability to carry oxygen in the blood. Hypertension (C) is high blood pressure, a condition where the force of the blood against the artery walls is too high. Diabetes (D) is a condition characterized by high blood sugar levels, either due to insufficient insulin production or the body's resistance to insulin, leading to various complications.
