1. Hampton's greatest achievement as the leader of the BPP may be his fight against street gang violence in Chicago. Which of these, if any, is misspelled?

• A. None of these is misspelled.
• B. greatest
• C. achievement
• D. leader

Correct answer: A

Rationale: All the words in the sentence are spelled correctly, including 'achievement.' There is no misspelling present. 'Greatest,' 'achievement,' and 'leader' are all spelled correctly. Option A is correct as there is no misspelled word in the sentence. Choices B, C, and D are wrong because they are correctly spelled words in the context of the sentence.

2. Which of the following substances has an acidic pH?

• A. Lemon juice
• B. Blood
• C. Urine
• D. Salt water

Correct answer: A

Rationale: The correct answer is A, Lemon juice, which has an acidic pH typically around 2 due to its citric acid content. Blood, urine, and salt water are not typically acidic in nature. Blood has a slightly basic pH, urine can vary but is usually slightly acidic to neutral, and salt water is neutral to slightly alkaline. Lemon juice is a commonly known acidic substance, often used in cooking and cleaning due to its acidic properties.

3. Which of these examples is a compound sentence?

• A. Alex and Shane spent the morning coloring and later took a walk down to the park.
• B. After coloring all morning, Alex and Shane spent the afternoon at the park.
• C. Alex and Shane spent the morning coloring, and then they took a walk down to the park.
• D. After coloring all morning and spending part of the day at the park, Alex and Shane took a nap.

Correct answer: C

Rationale: Option C is a compound sentence because it consists of two independent clauses joined by a coordinating conjunction ('and then'). The first independent clause is 'Alex and Shane spent the morning coloring,' and the second independent clause is 'they took a walk down to the park.' Choices A, B, and D are not compound sentences. In choice A, although there are two actions mentioned, they are not independent clauses; they are part of a single sentence. Choice B is a complex sentence with a dependent clause ('After coloring all morning') and an independent clause. Choice D is a complex sentence with a compound predicate ('After coloring all morning and spending part of the day at the park') followed by an independent clause.

4. 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.

5. What is the primary function of red blood cells?

• A. To transport nutrients
• B. To transport oxygen
• C. To fight infection
• D. To produce antibodies

Correct answer: B

Rationale: The correct answer is B: To transport oxygen. Red blood cells play a crucial role in carrying oxygen from the lungs to all the tissues and organs in the body. This oxygen transport is essential for cellular respiration, where oxygen is used in the production of energy. Red blood cells do not primarily transport nutrients, fight infection, or produce antibodies. Choice A is incorrect because while red blood cells do carry some nutrients, their primary function is to transport oxygen. Choice C is incorrect because immune cells, not red blood cells, are responsible for fighting infections. Choice D is incorrect as antibody production is mainly carried out by specialized white blood cells, not red blood cells.
