1. Which sentence correctly uses a semicolon?

• A. I have a big test tomorrow; I can't go out tonight.
• B. She likes apples; oranges are her favorite.
• C. I went to the store; and I bought some milk.
• D. I like apples, but oranges are better.

Correct answer: B

Rationale: The sentence 'She likes apples; oranges are her favorite.' correctly uses a semicolon to connect two related independent clauses. The semicolon is used to separate two closely related ideas in a way that is stronger than a comma but not as final as a period. Choice A is incorrect because the conjunction 'but' is missing before 'I can't go out tonight.' Choice C is incorrect as the conjunction 'and' after the semicolon is unnecessary and disrupts the flow of the sentence. Choice D is incorrect because the semicolon is incorrectly placed before 'oranges are better,' where a comma or period would be more appropriate.

2. Which type of muscle tissue is found in the walls of hollow organs?

• A. Skeletal muscle
• B. Cardiac muscle
• C. Smooth muscle
• D. Striated muscle

Correct answer: C

Rationale: Smooth muscle tissue is found in the walls of hollow organs such as the intestines, blood vessels, and bladder. It contracts involuntarily, allowing for functions like peristalsis in the intestines and regulation of blood flow in blood vessels. Skeletal muscle (Choice A) is attached to bones, cardiac muscle (Choice B) is found in the heart, and striated muscle (Choice D) refers to both skeletal and cardiac muscles due to their striped appearance, but neither of these types are typically found in the walls of hollow organs.

3. Which type of blood cell is primarily responsible for fighting infections?

• A. Red blood cells
• B. White blood cells
• C. Platelets
• D. Plasma

Correct answer: B

Rationale: White blood cells, also known as leukocytes, play a crucial role in the immune system by primarily combating infections. These cells can identify and destroy pathogens, such as bacteria and viruses, helping the body defend against illnesses and maintain overall health. Red blood cells are responsible for oxygen transport, platelets aid in blood clotting, and plasma carries various components throughout the circulatory system, but none of these functions involve fighting infections like white blood cells do.

4. What is the probability of rolling an even number on a six-sided die?

• A. 50%
• B. 16.70%
• C. 25%
• D. 33.30%

Correct answer: A

Rationale: The correct answer is A, 50%. A standard six-sided die has three even numbers (2, 4, 6) out of six possible outcomes. The probability of rolling an even number is therefore 3 out of 6, which simplifies to 50%. Choices B, C, and D are incorrect because they do not accurately reflect the probability of rolling an even number on a six-sided die.

5. A baker can bake 4 cakes with 10 cups of sugar. If he has a 30-cup bag that is half full, how many cakes can he bake?

• A. 6 cakes
• B. 5 cakes
• C. 7 cakes
• D. 8 cakes

Correct answer: A

Rationale: If the 30-cup bag is half full, it contains 15 cups of sugar. Since 10 cups are needed to bake 4 cakes, the baker can bake 4 * (15 / 10) = 6 cakes. Therefore, the correct answer is 6 cakes. Choice B, 5 cakes, is incorrect as it does not consider the correct sugar-to-cake ratio. Choices C and D are incorrect as they do not accurately calculate the number of cakes based on the available sugar.
