1. What is one point on which the scientist and politician agree?

• A. Burning fossil fuels causes global temperatures to rise.
• B. Global temperatures are increasing.
• C. Countries must revisit their energy policies before it's too late.
• D. Earth's climate naturally goes through warming and cooling periods.

Correct answer: B

Rationale: The correct answer is B: 'Global temperatures are increasing.' The scientist and politician both agree on this point based on the context provided. Choice A is incorrect because while it might be a common belief among scientists, the politician's agreement is not explicitly mentioned. Choice C is incorrect as it suggests a course of action rather than a point of agreement. Choice D is incorrect as it contradicts the consensus that global temperatures are currently increasing due to human activities, not just natural climate cycles.

2. Which phrase best completes the definition of a memoir?

• A. A historical account of a person's life written by one who has intimate knowledge of the person's life
• B. A historical account of a person's life written by the person himself or herself
• C. A fictional account about a famous person
• D. A nonfictional account about a famous person without factual reference

Correct answer: A

Rationale: A memoir is a historical account of a person's life written by someone who has intimate knowledge of that person's life, not necessarily by the person themselves. This distinguishes it from an autobiography, which is written by the person themselves. Memoirs are nonfictional and based on factual references, making option A the most fitting completion of the definition. Choices B, C, and D are incorrect because a memoir is not necessarily written by the person about whom it is written, it is not fictional, and it should be based on factual references to be considered a memoir.

3. A couple dining at a restaurant receives a bill for $58.60. They wish to leave a 16% gratuity. Which of the following is the estimated gratuity?

• A. $8.48
• B. $6.40
• C. $9.38
• D. $7.00

Correct answer: C

Rationale: To calculate a 16% gratuity on a bill of $58.60, you multiply $58.60 by 0.16, which equals $9.376. Rounding this to the nearest cent gives $9.38. Therefore, the estimated gratuity is $9.38. Choice A is incorrect as it does not accurately reflect the calculated amount. Choice B is also incorrect as it does not match the correct calculation. Choice D is incorrect as it is not the nearest estimated value to the calculated amount.

4. Which structure contains the genetic material (DNA) of the cell?

• A. Cytoplasm
• B. Nucleus
• C. Cell wall (only present in plant cells)
• D. Golgi apparatus

Correct answer: B

Rationale: The nucleus is the organelle that contains the genetic material (DNA) of the cell. It acts as the control center of the cell, regulating gene expression and coordinating cellular activities. The cytoplasm is the fluid-filled space within the cell where organelles are suspended, but it does not contain the genetic material. The cell wall is a rigid structure found in plant cells that provides support and protection, but it does not house the DNA. The Golgi apparatus is involved in processing and packaging proteins for secretion, but it does not contain the genetic material of the cell.

5. What is correct about the hormones that stimulate male and female organs to produce male and female sex hormones?

• A. Female organs are stimulated by female hormones and male organs by male hormones.
• B. The same hormones that produce male or female sex characteristics stimulate the organs.
• C. The same hormones stimulate both male and female organs to produce sex hormones.
• D. The hypothalamus stimulates the pituitary gland's secretion of male and female hormones.

Correct answer: C

Rationale: The correct answer is C. The same hormones stimulate both male and female organs to produce sex hormones. Hormones such as luteinizing hormone (LH) and follicle-stimulating hormone (FSH) are produced by the pituitary gland and act on the ovaries in females and the testes in males to stimulate the production of sex hormones (estrogen and progesterone in females, testosterone in males). Therefore, the same hormones stimulate both male and female organs to produce sex hormones. Choices A, B, and D are incorrect because they do not accurately describe the relationship between hormones and the stimulation of male and female organs to produce sex hormones.
