1. What is a factor?
- A. A number that you multiply to get another number
- B. A number that divides evenly into another number
- C. A number that can be both multiplied and divided by another number
- D. A number that is greater than 1
Correct answer: A
Rationale: A factor is a number that can be multiplied by another number to produce a third number. When you multiply factors together, you get the original number. For example, the factors of 12 are 1, 2, 3, 4, 6, and 12 because these numbers can be multiplied in pairs to give the product 12. Choice B is incorrect as it describes a divisor. Choice C is incorrect because factors are only multiplied, not divided. Choice D is incorrect because factors can be any number, not just those greater than 1.
2. What is the primary function of nephrons?
- A. Store urine
- B. Filter blood and remove waste products
- C. Produce hormones
- D. Control blood pressure
Correct answer: B
Rationale: Nephrons are the functional units of the kidneys responsible for filtering blood to remove waste products, excess ions, and water. This process leads to the formation of urine, aiding in maintaining the body's fluid and electrolyte balance. The primary function of nephrons is not to store urine but to filter blood and eliminate waste products. Choice C, 'Produce hormones,' is incorrect as nephrons primarily focus on filtration rather than hormone production. Choice D, 'Control blood pressure,' is also incorrect as while the kidneys do play a role in regulating blood pressure, it is not the primary function of nephrons within the kidneys.
3. The value of 6 x 12 is the same as:
- A. 2 x 4 x 4 x 2
- B. 7 x 4 x 3
- C. 6 x 6 x 3
- D. 3 x 3 x 4 x 2
Correct answer: A
Rationale: To find the value of 6 x 12, we multiply 6 by 12, which equals 72. A: 2 x 4 x 4 x 2 = 32 B: 7 x 4 x 3 = 84 C: 6 x 6 x 3 = 108 D: 3 x 3 x 4 x 2 = 72 Therefore, the correct answer is A, as the product of 2 x 4 x 4 x 2 equals 32, which is the same as 6 x 12.
4. Which of the following would be a useful source of information to determine the validity of the argument presented in the passage?
- A. A survey of high school students' preferences regarding foreign language requirements.
- B. A comparison of the correlation between a second language introduced at home and subsequent college acceptance rates.
- C. A survey asking parents to select the foreign language they would like their children to study in high school.
- D. A comparison of the correlation between high school students' study of a foreign language and subsequent college acceptance rates.
Correct answer: D
Rationale: The passage emphasizes the importance of studying a foreign language in high school for future success, including college acceptance rates and job market demand. To evaluate the argument's validity, it is crucial to examine the direct impact of studying a foreign language on college acceptance rates. Choice D is the correct answer because it directly addresses this aspect by comparing the correlation between high school students' study of a foreign language and subsequent college acceptance rates. This comparison would provide concrete evidence supporting or refuting the argument presented in the passage. Choices A, B, and C, though related to language education, do not directly assess the specific relationship between studying a foreign language in high school and college acceptance rates, making them less relevant for evaluating the argument's validity.
5. What is the primary function of DNA polymerase?
- A. Packaging DNA
- B. Replicating DNA
- C. Transcribing DNA
- D. Translating mRNA
Correct answer: B
Rationale: The correct answer is B: Replicating DNA. DNA polymerase is an enzyme responsible for synthesizing new DNA strands during DNA replication. It adds nucleotides to the growing DNA strand based on the template provided by the existing DNA strand. This process ensures that genetic information is accurately copied and passed on to daughter cells during cell division. Option A, Packaging DNA, refers to the coiling and organization of DNA into chromatin, a process involving histones and other proteins. Option C, Transcribing DNA, involves the synthesis of RNA from a DNA template, a process carried out by RNA polymerase. Option D, Translating mRNA, refers to the process of protein synthesis where the information encoded in mRNA is used to assemble amino acids into a polypeptide chain.
