1. What is the mass number of an element?

• A. The number of protons in an atom's nucleus.
• B. The number of neutrons in an atom's nucleus.
• C. The number of electrons in an atom's valence shell.
• D. The number of isotopes of an element.

Correct answer: B

Rationale: The mass number of an element represents the total number of protons and neutrons in an atom's nucleus. It specifically focuses on the number of neutrons in an atom's nucleus, which contributes to the overall mass of the atom. Therefore, the mass number is not solely determined by the number of protons, electrons, or isotopes. Choice A is incorrect because it refers to the atomic number, which is the number of protons in an atom's nucleus. Choice C is incorrect as the number of electrons in the valence shell is related to the atom's reactivity and bonding behavior, not the mass number. Choice D is incorrect because the mass number does not represent the number of isotopes of an element, but rather the sum of protons and neutrons in an atom's nucleus. Thus, option B, the number of neutrons in an atom's nucleus, is the correct choice.

2. Which of the following is the most reliable source for scholarly research?

• A. Peer-reviewed articles
• B. Wikipedia
• C. Opinion articles from a newspaper
• D. Blogs and other social media

Correct answer: A

Rationale: The correct answer is 'Peer-reviewed articles.' Peer-reviewed articles are considered highly reliable because they undergo a rigorous evaluation process by experts in the field before publication. This process ensures that the research presented is of high quality and meets academic standards. Choice B, 'Wikipedia,' is not considered a reliable source for scholarly research as it can be edited by anyone, leading to potential inaccuracies. Choice C, 'Opinion articles from a newspaper,' may provide perspectives but may not always be based on rigorous research or evidence. Choice D, 'Blogs and other social media,' lack the rigorous review process that peer-reviewed articles undergo, making them less reliable for scholarly research.

3. Identify the type of clause in the sentence 'When the clock struck midnight, the magic began.'

• A. Main clause
• B. Subordinate clause
• C. Appositive clause
• D. Noun clause

Correct answer: B

Rationale: The clause 'When the clock struck midnight' is a subordinate clause because it does not express a complete thought on its own and depends on the main clause 'the magic began' to form a complete sentence. Subordinate clauses typically begin with subordinating conjunctions like 'when,' 'if,' 'because,' etc., and serve to provide additional information or context to the main clause. Choice A, 'Main clause,' is incorrect because the highlighted clause is not the primary clause that provides the main idea. Choice C, 'Appositive clause,' is incorrect as an appositive clause renames or explains a noun in the sentence, which is not the case here. Choice D, 'Noun clause,' is incorrect as a noun clause functions as a noun within a sentence, and the highlighted clause does not act as a noun but rather as a dependent clause providing contextual information.

4. Which organ produces insulin?

• A. Pancreas
• B. Liver
• C. Stomach
• D. Kidneys

Correct answer: A

Rationale: Insulin is a hormone that regulates blood sugar levels by facilitating the uptake of glucose into cells for energy production or storage. The pancreas, located behind the stomach, is the organ responsible for producing insulin. Within the pancreas, specialized cells known as beta cells synthesize and secrete insulin in response to changes in blood glucose levels. The liver, although vital for metabolism, does not produce insulin. Similarly, the stomach and kidneys do not play a role in insulin production. Hence, the correct answer is the pancreas.

5. Julie Walker-Mayfield plans to register for fall classes at Chatham College. She works during the day and doesn't get off work until 5:30 PM. She also has no internet access at work and will have to register for classes once she gets home. Taking into account her personal schedule and the registration schedule provided by the college, when will she be able to go online to enter the registration system and select her classes?

• A. Monday, 10 AM-12 PM
• B. Monday, 5-7 PM
• C. Tuesday, 5-7 PM
• D. Tuesday, 8-10 PM

Correct answer: C

Rationale: Julie Walker-Mayfield doesn't get off work until 5:30 PM, so she won't be able to register for classes until she gets home. Considering she needs time to unwind after work and settle in, the earliest and most suitable time for her to enter the registration system and select her classes is Tuesday, 5-7 PM. Choice A is incorrect as it falls on Monday, and she gets off work at 5:30 PM. Choices B and D are also incorrect as she needs time to settle in after work before going online to register.
