1. During ejaculation, sperm travels through a tube from the testes to the urethra. What is the name of this tube?

• A. Vas deferens
• B. Epididymis
• C. Seminal vesicle
• D. Urethra

Correct answer: A

Rationale: The vas deferens is the correct answer. It is the tube that carries sperm from the testes to the urethra during ejaculation. The vas deferens plays a crucial role in transporting mature sperm for ejaculation. The epididymis is responsible for sperm maturation and storage, not the direct passage of sperm to the urethra. The seminal vesicle produces fluid that combines with sperm to form semen but is not the tube for sperm transport. The urethra serves as the passageway for both urine and semen out of the body but is not the specific tube that transports sperm from the testes to the urethra.

2. What is the main function of red blood cells?

• A. Transport oxygen
• B. Transport carbon dioxide
• C. Regulate blood pressure
• D. Regulate heart rate

Correct answer: A

Rationale: The correct answer is A: Transport oxygen. Red blood cells are primarily responsible for carrying oxygen from the lungs to the tissues in the body. Hemoglobin, a protein found in red blood cells, binds to oxygen in the lungs and releases it to cells throughout the body. This oxygen transport is essential for cellular respiration and energy production in the body. Red blood cells do not regulate blood pressure or heart rate; their main role is oxygen transport. Choices B, C, and D are incorrect because red blood cells do not transport carbon dioxide, regulate blood pressure, or regulate heart rate. These functions are primarily carried out by other components of the circulatory and regulatory systems.

3. What is the librarian's best course of action in this situation?

• A. The librarian shows the student how to do an Internet search using Google
• B. Since the assignment is to read a biography, the librarian directs the student to the biography section of the library rather than to the Internet. She helps the student select a biography at his reading level
• C. The librarian directs the student to a database that will quickly provide a list of resources and articles pertaining to Thomas Jefferson
• D. The librarian searches her computerized records, decides that none of the biographies in her school library are appropriate for this student, and initiates an inter-library loan. The borrowed biography will take about two weeks to arrive

Correct answer: B

Rationale: The librarian's best course of action in this situation is to direct the student to the biography section of the library because the assignment specifically requires the student to read a biography. By helping the student select a biography at his reading level, the librarian ensures that the student is staying on task and fulfilling the assignment requirements. This approach also encourages the student to engage with physical books rather than relying solely on the Internet for research. Choice A is incorrect because it deviates from the assignment's requirement of reading a biography. Choice C is not the best option as it overlooks the specificity of the assignment and may lead the student away from the required task. Choice D is not ideal as it involves a lengthy process of inter-library loan which may not be necessary if suitable biographies are available in the library.

4. What type of sentence is the following: 'If it rains tomorrow, the picnic will be canceled'?

• A. Simple
• B. Compound
• C. Complex
• D. Compound-complex

Correct answer: C

Rationale: The given sentence, 'If it rains tomorrow, the picnic will be canceled,' is a complex sentence. It consists of an independent clause 'the picnic will be canceled' and a dependent clause 'If it rains tomorrow.' A simple sentence contains just one independent clause, a compound sentence contains two or more independent clauses, and a compound-complex sentence contains two or more independent clauses and at least one dependent clause. Therefore, choices A, B, and D are incorrect for this sentence.

5. What is the equivalent of 35.4 centimeters in kilometers (km)?

• A. 0.00354 km
• B. 0.000354 km
• C. 0.00345 km
• D. 0.0345 km

Correct answer: B

Rationale: To convert centimeters to kilometers, you need to divide by 100,000 since there are 100,000 centimeters in a kilometer. Therefore, 35.4 cm ÷ 100,000 = 0.000354 km. Choice A (0.00354 km) is incorrect as it represents dividing by 10,000, not 100,000. Choice C (0.00345 km) is incorrect as the last digit is different from the correct answer. Choice D (0.0345 km) is incorrect as it represents dividing by 1,000, not by 100,000.
