1. Even without Franz Ferdinand's assassination ... Which of the following most logically completes the passage?

• A. A war between the world powers was extremely likely.
• B. World War I never would have happened.
• C. England, France, and Russia would have started the war.
• D. Austria would have started the war.

Correct answer: A

Rationale: The correct answer is A. Given the alliances and tensions at the time, the assassination was simply the trigger in an already volatile situation, making war highly likely. Choice B is incorrect because the alliances and existing tensions would likely have led to a conflict even without the assassination. Choice C is incorrect as it wrongly implies that only these three countries were involved in the conflict. Choice D is incorrect as Austria alone starting the war doesn't consider the broader context of alliances and power dynamics among the world powers.

2. What is the primary function of the cell membrane?

• A. To provide structural support for the cell
• B. To transport substances in and out of the cell
• C. To synthesize proteins and lipids
• D. To store genetic material

Correct answer: B

Rationale: The primary function of the cell membrane, also known as the plasma membrane, is to regulate the movement of substances in and out of the cell. It acts as a selectively permeable barrier, allowing specific molecules to pass through while blocking others. This role is crucial for maintaining the internal environment of the cell by enabling essential nutrients to enter and waste products to exit. While the cell membrane provides some structural support for the cell, its main function is substance transport. Protein and lipid synthesis predominantly occur in organelles like the endoplasmic reticulum and Golgi apparatus, and storing genetic material is the nucleus's responsibility. Therefore, choices C (To synthesize proteins and lipids) and D (To store genetic material) are incorrect as these functions are carried out by other cell organelles, not the cell membrane.

3. Which hormone is crucial for stimulating sperm production in males?

• A. Estrogen
• B. Progesterone
• C. Testosterone
• D. Insulin

Correct answer: C

Rationale: Testosterone is the hormone crucial for stimulating sperm production in males. It is primarily produced in the testes and plays a significant role in the development of male reproductive tissues, including the testes and prostate, as well as promoting secondary sexual characteristics such as facial hair growth and deepening of the voice. Estrogen and progesterone are female sex hormones responsible for regulating the menstrual cycle and other female reproductive functions. Insulin, on the other hand, is involved in regulating blood sugar levels and glucose metabolism, not directly related to sperm production in males.

4. In which of the following word pairs does the noun become a verb when the suffix is added?

• A. Biology, Biologist
• B. Apology, Apologize
• C. Happy, Happily
• D. Mineral, Mineralogy

Correct answer: B

Rationale: The correct answer is B. 'Apology' transforms into 'apologize' when the suffix is added, changing the word from a noun to a verb. In this case, the suffix '-ize' is added to the noun 'apology' to form the verb 'apologize.' Choices A, C, and D do not involve a transformation from a noun to a verb when a suffix is added. 'Biology' and 'biologist' are related but not in a noun-to-verb transformation. 'Happy' and 'happily' involve an adjective-to-adverb transformation. 'Mineral' and 'mineralogy' are related terms in the same field but do not show a noun-to-verb change.

5. Which represents the correct order of airflow in the lungs?

• A. Bronchi, trachea, alveoli, bronchioles
• B. Alveoli, bronchioles, bronchi, trachea
• C. Trachea, bronchi, bronchioles, alveoli
• D. Bronchioles, alveoli, trachea, bronchi

Correct answer: C

Rationale: The correct order of airflow in the lungs starts with air entering through the trachea, moving into the bronchi, then proceeding to the bronchioles, and finally reaching the alveoli where gas exchange occurs. Therefore, the correct sequence is Trachea, Bronchi, Bronchioles, Alveoli, making choice C the accurate representation of the airflow in the lungs. Choices A, B, and D are incorrect because they do not follow the anatomical path of airflow in the lungs as air moves from the trachea to the bronchi, then bronchioles, and finally the alveoli for gas exchange.
