1. Which of the following nutrients is correctly matched with its foundational components?

A. Carbohydrates are formed when glucose molecules bond together.
B. Lipids consist of fatty acids and glycerol.
C. Nucleic acids consist of nitrogenous bases, sugar, and phosphate groups.
D. Proteins consist of strings of amino acids.

Correct answer: D

Rationale: Proteins consist of strings of amino acids. Amino acids are the basic building blocks of proteins, and they are linked together in a specific sequence to form a protein structure. This is a correct match between the nutrient (proteins) and its foundational components (amino acids). Choices A, B, and C are incorrect as they do not accurately match the foundational components of the respective nutrients. Carbohydrates are not formed by glucose molecules bonding together; they are made up of sugar molecules. Lipids consist of fatty acids and glycerol, but they are not nutrients typically associated with bonding for formation. Nucleic acids do consist of nitrogenous bases, sugar, and phosphate groups, but they are not the correct match for the question.

2. Convert 0.07 to a fraction.

A. 7/100
B. 1/10
C. 1/20
D. 1/50

Correct answer: A

Rationale: To convert 0.07 to a fraction, we note that 0.07 is equivalent to 7/100. This is because 0.07 can be read as 7 hundredths. Thus, the correct fraction form is 7/100. Choices B, C, and D are incorrect. Choice B, 1/10, is the fraction equivalent to 0.1, not 0.07. Choice C, 1/20, and Choice D, 1/50, are also incorrect as they do not represent the value of 0.07 when converted to a fraction.

3. How many milliliters are in 1 ounce?

A. 20 ml
B. 30 ml
C. 40 ml
D. 50 ml

Correct answer: B

Rationale: The correct answer is B: 30 ml. 1 ounce is equivalent to 30 milliliters. This conversion is a common one in many contexts involving liquid measurements. Choice A (20 ml), Choice C (40 ml), and Choice D (50 ml) are incorrect conversions and do not represent the accurate conversion between ounces and milliliters.

4. The student feared she would fail, so she thought she should study harder. Which of the following is a correct revision of the ambiguous sentence above?

A. Unless the student feared that she would fail out of school, she wouldn’t study harder.
B. The student said, 'she will fail out of the university unless she studies during her exams.'
C. The student was afraid that she should study harder before failing out during her exams.
D. 'If I don’t study harder before the exams,' the student fretted, 'I will surely fail out of school.'

Correct answer: D

Rationale: Option D is the clearest revision as it expresses the student's concern directly through dialogue. The use of quotation marks provides clarity, and the student's worry about failing is stated clearly. The other options either lack clarity or contain grammatical issues. Option A introduces an unnecessary condition with 'unless' which changes the original meaning. Option B introduces a third-person perspective that is not present in the original sentence. Option C is awkwardly constructed and does not convey the student's concern effectively.

5. Convert 0.2 liters to milliliters. What is the equivalent volume?

A. 20 ml
B. 200 ml
C. 2 ml
D. 2000 ml

Correct answer: B

Rationale: To convert 0.2 liters to milliliters, you need to multiply by 1,000 because there are 1,000 milliliters in a liter. So, 0.2 * 1,000 = 200 milliliters. Therefore, the correct answer is 200 ml. Choice A (20 ml) is incorrect because it represents 0.02 liters, not 0.2 liters. Choice C (2 ml) is incorrect as it represents 0.002 liters. Choice D (2000 ml) is incorrect as it represents 2 liters, not 0.2 liters.
