1. When ethanol (C₂H₅OH) reacts with sodium metal (Na), what is the product?

• A. Ethene (C₂H₄)
• B. Sodium ethoxide (C₂H₅ONa)
• C. Ethane (C₂H₆)
• D. Sodium acetate (CH₃COONa)

Correct answer: B

Rationale: When ethanol (C₂H₅OH) reacts with sodium metal (Na), the product formed is Sodium ethoxide (C₂H₅ONa). This reaction is a classic example of a metal displacing hydrogen in an alcohol to form an alkoxide. In this specific case, sodium replaces the hydrogen in ethanol, resulting in the formation of sodium ethoxide. Choice A, Ethene (C₂H₄), is incorrect as it is a different compound formed from the dehydration of ethanol, not its reaction with sodium. Choice C, Ethane (C₂H₆), is incorrect as it is a saturated hydrocarbon, not the product of the reaction of ethanol with sodium metal. Choice D, Sodium acetate (CH₃COONa), is incorrect as it involves acetic acid, not ethanol, reacting with sodium to form the salt sodium acetate.

2. Write a research report about a national park in the United States that is experiencing threats.

• A. Florida's Everglades National Park is threatened with a rising sea level as restoration efforts lag.
• B. The Grand Canyon is a steep-sided canyon carved by the Colorado River in Arizona, United States.
• C. Every year someone falls over the edge of Going-to-the-Sun Road at Glacier National Park.
• D. My visit to Acadia National Park last summer was one of the most interesting trips I've ever taken.

Correct answer: A

Rationale: Choice A is the correct answer as it directly addresses the writing prompt by focusing on a specific threat faced by a national park in the United States, which is the rising sea level affecting Florida's Everglades National Park. This choice provides a clear thesis statement for a research report on the topic. Choices B, C, and D are incorrect. Choice B provides general information about the Grand Canyon but does not discuss any threats it is facing. Choice C is not relevant to the prompt as it talks about accidents on a specific highway within Glacier National Park rather than broader threats to the park itself. Choice D is about a personal experience at Acadia National Park and does not address any threats the park may be experiencing.

3. Which pronoun correctly replaces the phrase Sarah and me in the sentence: 'Jessica invited Sarah and me to the party, but I forgot to respond to her.'

• A. We
• B. Us
• C. Ours
• D. Myself

Correct answer: B

Rationale: The correct answer is 'B: Us.' In the sentence, 'Jessica invited Sarah and me to the party,' 'Sarah and me' serve as the object of the verb 'invited.' Therefore, the pronoun 'us' is the correct choice to replace 'Sarah and me' as the object pronoun. Choice A, 'We,' is a subject pronoun and does not fit in this context. Choice C, 'Ours,' is a possessive pronoun and is not appropriate for replacing the object pronoun 'Sarah and me.' Choice D, 'Myself,' is a reflexive pronoun, which is not suitable for this sentence where an object pronoun is needed.

4. A study was conducted where patients were divided into three groups: 1/2 in Group Alpha, 1/3 in Group Beta, and 1/6 in Group Gamma. Which group is the smallest?

• A. Group Alpha
• B. Group Beta
• C. Group Gamma
• D. Group Gamma

Correct answer: C

Rationale: The smallest group is Group Gamma, which had 1/6 of the total number of patients. To determine the smallest group, compare the fractions representing the portions of patients in each group. 1/6 is smaller than 1/3 and 1/2, making Group Gamma the smallest. Group Alpha and Group Beta have larger fractions of patients, making them larger groups compared to Group Gamma.

5. In a study on anorexia, 100 patients participated. Among them, 70% were women, and 10% of the men were overweight as children. How many male patients in the study were not overweight as children?

• A. 3
• B. 10
• C. 27
• D. 30

Correct answer: C

Rationale: Out of the 100 patients, 30% were men. Since 10% of the men were overweight as children, 90% of the male patients were not overweight. Therefore, the number of male patients not overweight as children can be calculated as 30 (total male patients) x 0.90 = 27. Choices A, B, and D are incorrect because they do not accurately calculate the number of male patients who were not overweight as children based on the given information.
