1. Where does most of the chemical digestion take place?

• A. Large intestine
• B. Stomach
• C. Small intestine
• D. Esophagus

Correct answer: C

Rationale: Most of the chemical digestion occurs in the small intestine. Enzymes in the small intestine break down nutrients into smaller molecules that can be absorbed by the body. The stomach plays a role in digestion by breaking down food mechanically and initiating some chemical digestion, but the majority of nutrient breakdown and absorption happens in the small intestine. The large intestine mainly absorbs water and salts, with little to no digestion taking place there. The esophagus is a muscular tube that helps move food from the mouth to the stomach and does not participate in digestion.

2. Hampton was born and raised in Maywood of Chicago, Illinois in 1948. Which of the following is the correct punctuation for the sentence?

• A. NO CHANGE
• B. in Maywood, of Chicago, Illinois in 1948.
• C. in Maywood of Chicago, Illinois, in 1948.
• D. in Chicago, Illinois of Maywood in 1948.

Correct answer: C

Rationale: Option C correctly punctuates the sentence by placing commas after 'Chicago' and 'Illinois' to separate the location details and inserting a comma before 'in 1948' to separate the location from the date. This creates a clear and grammatically correct sentence. Choices A, B, and D incorrectly place the commas, leading to confusion or incorrect grouping of the location and date information.

3. Which of the following conclusions is well supported by the passage?

• A. The Human Resources team will take longer than initially stated to review candidates and schedule interviews for the position of Lead Technician.
• B. Mr. Morgan is well qualified for the position of Lead Technician and will likely be offered an interview.
• C. The Human Resources team may struggle to find a suitable candidate for the position of Lead Technician due to the high number of applications received.
• D. Mr. Morgan will patiently wait for further communication from the Human Resources team regarding his application for the position of Lead Technician.

Correct answer: B

Rationale: The passage mentions that Mr. Morgan's application for the position of Lead Technician has been received, along with a higher-than-expected number of applications. It also states that the Human Resources team will take longer than previously stated to review candidates and schedule interviews. While there is no direct mention of Mr. Morgan's qualifications or the likelihood of him being offered an interview, it can be inferred that his interest in the position and the competitive application pool suggest that he is well qualified and stands a good chance of being offered an interview. Therefore, the most supported conclusion is that Mr. Morgan is well qualified for the position of Lead Technician and will likely be offered an interview. Choice A is incorrect because the passage does not mention the specific timeframe within which Mr. Morgan was informed about receiving feedback. Choice C is not directly supported by the passage as it does not indicate any challenges in finding a qualified candidate. Choice D is not directly addressed in the passage and is speculative.

4. Which of the following is NOT a greenhouse gas?

• A. Carbon Dioxide
• B. Methane
• C. Oxygen
• D. Water Vapor

Correct answer: C

Rationale: A) Carbon Dioxide: Carbon dioxide is a greenhouse gas released into the atmosphere through various human activities such as burning fossil fuels and deforestation. It contributes to global warming by trapping heat in the atmosphere. B) Methane: Methane is another greenhouse gas released from sources like livestock, landfills, and natural gas production. It is more potent than carbon dioxide in trapping heat. C) Oxygen: Oxygen is not considered a greenhouse gas. It is a vital component of the Earth's atmosphere necessary for respiration and combustion, but it does not trap heat like greenhouse gases do. D) Water Vapor: Water vapor is a significant greenhouse gas that plays a crucial role in the Earth's climate system by trapping heat in the atmosphere. It is the most abundant greenhouse gas. Therefore, the correct answer is C) Oxygen, as it is not a greenhouse gas.

5. What is the simplified form of the expression (x^2 + 2x)/(x)?

• A. x + 2
• B. x^2 + 2
• C. x(x + 2)
• D. 1 + 2/x

Correct answer: A

Rationale: To simplify the expression (x^2 + 2x)/(x), we factor out x from the numerator to get x(x + 2) and then cancel the x in the denominator. This simplifies to x + 2, making choice A the correct answer. Choice B (x^2 + 2) is incorrect as it does not account for the division by x. Choice C (x(x + 2)) is also incorrect as it represents the factored form before cancellation. Choice D (1 + 2/x) is incorrect as it does not simplify the expression correctly.
