1. An uncharged atom has an electron configuration of 1s² 2s² 2p⁶ 3s² and a mass number of 14. How many protons does it have?

• A. 14
• B. 6
• C. 8
• D. 12

Correct answer: B

Rationale: The number of protons in an atom is determined by the atomic number, which is equal to the number of protons in the nucleus. The electron configuration given corresponds to carbon (C) with 6 protons. The atomic number of an element is the same as the number of protons in its nucleus, so in this case, the atom has 6 protons. Choices A, C, and D are incorrect because they do not correspond to the correct number of protons for an atom with the given electron configuration and mass number. Therefore, option B, 6 protons, is the correct answer.

2. Which structure allows for the selective passage of materials into and out of the cell?

• A. DNA
• B. Protein
• C. Carbohydrate
• D. Phospholipid bilayer

Correct answer: D

Rationale: The phospholipid bilayer is a crucial component of the cell membrane, surrounding the cell and regulating the passage of materials into and out of the cell. Its structure enables it to be selectively permeable, controlling which substances can pass through. DNA, proteins, and carbohydrates are essential molecules in the cell but do not directly govern the passage of materials like the phospholipid bilayer does. Therefore, the correct answer is the phospholipid bilayer.

3. What is the medical term for a urinary tract infection (UTI)?

• A. Nephritis
• B. Cystitis
• C. Urethritis
• D. All of the above

Correct answer: B

Rationale: The medical term specifically used to refer to a urinary tract infection (UTI) that affects the bladder is cystitis. Nephritis refers to inflammation of the kidneys, and urethritis refers to inflammation of the urethra. As such, cystitis is the correct term for a UTI, making choice B the right answer. Choices A, C, and D are incorrect because they refer to different conditions affecting the urinary system.

4. According to the extract, which of the following statements most closely correlates with the definition of the term 'working man'?

• A. A working man is someone who is well versed in the workings of the soul.
• B. A working man is probably not involved in social activities due to the high physical demand of work.
• C. A working man is someone who earns wages in a traditional sense, often associated with the middle class.
• D. The working man historically transitions from the field to the factory and now to the screen.

Correct answer: C

Rationale: According to the extract, the term 'working man' refers to individuals who are actively employed and earn wages in a traditional sense. Charles Dickens emphasizes the importance of the working man having a share in the management of institutions designed for their benefit. This aligns with choice C, making it the correct answer. Choice A is incorrect as the extract does not mention anything about being well versed in the workings of the soul. Choice B is incorrect because the extract does not suggest that working men are not involved in social activities due to the physical demands of their work. Choice D is also incorrect as the extract does not focus on the historical transitions of the working man.

5. She is a gifted pianist, although she's struggling with the piece for her upcoming concert.

• A. Inappropriate transition word choice
• B. Poor diction
• C. Tense disagreement
• D. Incomplete sentence

Correct answer: C

Rationale: The correct answer is C because there is a tense disagreement in the sentence. The use of 'was' (past tense) and 'she's' (contraction of 'she is' present tense) creates an inconsistency in the verb tense. The sentence should maintain consistency either in past tense ('She was a gifted pianist, although she struggled with the piece for her upcoming concert') or present tense ('She is a gifted pianist, although she's struggling with the piece for her upcoming concert'). Choices A, B, and D are incorrect as the issue in the sentence is related to verb tense disagreement, not transition words, diction, or sentence completeness.
