1. Two mice are both heterozygous for two traits: white fur (Ww) and short fur (Ss). Their offspring are most likely to have which of the following genotypes for these traits?

• A. wwss
• B. WWSS
• C. WwSs
• D. WWSs

Correct answer: C

Rationale: When two mice that are heterozygous for white fur (Ww) and short fur (Ss) mate, they can produce offspring with different combinations of the two traits. The Punnett square for this cross shows that the most likely genotype for the offspring is WwSs. In this case, each offspring receives one allele for white fur (W) and one for short fur (S) from each parent, resulting in a heterozygous genotype for both traits. Choice A (wwss) is incorrect as it represents a homozygous recessive genotype for both traits. Choice B (WWSS) is also incorrect as it represents a homozygous dominant genotype for both traits. Choice D (WWSs) is incorrect as it represents a genotype where one trait is homozygous dominant (W) and the other is heterozygous (S), which is not the most likely outcome based on the given parental genotypes.

2. Which type of evidence is used in the passage?

• A. emotional evidence
• B. appeal to authority
• C. specific evidence
• D. rhetorical questioning

Correct answer: C

Rationale: The passage uses specific evidence to support its claims. It presents factual information about the impact of private tutoring on students' grades, including a comparison of GPAs between students who had different types of tutoring. This specific evidence strengthens the argument by providing concrete data and examples. Emotional evidence, appeal to authority, and rhetorical questioning are not used in this passage, as it primarily relies on data and analysis to make its case.

3. What most likely describes the relationship between the author and Alan?

• A. competitive
• B. formal
• C. friendly
• D. caring

Correct answer: C

Rationale: The most likely description of the relationship between the author and Alan is friendly. The author's message to Alan is filled with warmth, concern, and offers of help, indicating a positive and supportive tone. The use of phrases like 'I just wanted to drop you a quick note' and 'Let me know if you want any special treats' reflect a friendly and amicable relationship. Choices A, B, and D are not as suitable as competitive, formal, or caring relationships do not align as strongly with the friendly and supportive nature of the interaction described in the text.

4. First and foremost, they receive an annual pension payment. T has been reviewed and changed a number of times, most recently to reflect the salary of a high-level government executive. Which of the following would NOT be an acceptable way to revise and combine the underlined portion of the sentences above?

• A. annual pension payment, the amount of which
• B. annual pension payment; the amount of the pension
• C. annual pension payment; over the years since 1958, the amount of the pension
• D. annual pension payment, the amount of the pension.

Correct answer: C

Rationale: Option C is the correct answer because it disrupts the flow of the sentence and introduces unnecessary information. The phrase 'over the years since 1958' is irrelevant in this context and does not contribute to the intended meaning of the sentence. The sentence is focused on the recent changes to the pension, not its historical evolution. Choices A, B, and D provide clear and concise ways to revise and combine the underlined portion of the sentences, maintaining a logical and relevant sentence structure.

5. Mandy can buy 4 containers of yogurt and 3 boxes of crackers for $9.55. She can buy 2 containers of yogurt and 2 boxes of crackers for $5.90. How much does one box of crackers cost?

• A. $1.75
• B. $2.00
• C. $2.25
• D. $2.50

Correct answer: C

Rationale: To solve this problem, we can set up a system of equations. Let the cost of one container of yogurt be y and the cost of one box of crackers be c. From the first scenario, we have 4y + 3c = 9.55. From the second scenario, we have 2y + 2c = 5.90. Solving these equations simultaneously, we find that c = $2.25. Therefore, one box of crackers costs $2.25. Choice A, $1.75, is incorrect because it does not satisfy the given conditions in the system of equations. Choice B, $2.00, is incorrect as it does not match the calculated solution. Choice D, $2.50, is incorrect as it does not align with the calculated value for one box of crackers.
