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. Which of the following glands produces hormones that regulate metabolism?

• A. Adrenal gland
• B. Pituitary gland
• C. Thyroid gland
• D. Liver

Correct answer: C

Rationale: The thyroid gland is responsible for producing hormones that play a crucial role in regulating metabolism. One of the key hormones produced by the thyroid gland is thyroxine, which directly influences the body's metabolic rate. Therefore, the correct answer is the thyroid gland. The adrenal gland produces hormones like adrenaline, which are associated with the stress response and not primarily metabolic regulation. The pituitary gland regulates various other hormones but is not primarily responsible for metabolic regulation. The liver has a role in metabolism, mainly in processes like detoxification and nutrient storage, but it is not a gland that primarily produces hormones for metabolic regulation, making it an incorrect choice in this context.

3. Which of the following best defines the word circumvent?

• A. To go around
• B. To go under
• C. To come near
• D. To come through

Correct answer: A

Rationale: The correct answer is A: 'To go around.' Circumvent means to find a way around an obstacle or to avoid something by cleverness or deception. Choice B, 'To go under,' is incorrect as circumvent does not involve going under something. Choice C, 'To come near,' is incorrect as circumvent does not mean to approach or get close to something. Choice D, 'To come through,' is incorrect as circumvent does not involve passing through something.

4. Which of the following is the base that will bind with cytosine?

• A. Adenine
• B. Cytosine
• C. Guanine
• D. Thymine

Correct answer: A

Rationale: Adenine is the correct answer as it is the base that binds with cytosine through hydrogen bonding in DNA, forming the A-T base pair. Cytosine always pairs with guanine to form the G-C base pair. Thymine pairs with adenine in DNA, not with cytosine.

5. Which statement is true regarding the process of digestion?

• A. Digestion of starch begins in the mouth.
• B. Amylase is produced by the stomach to help break down food in the upper intestine.
• C. The di- and tri-saccharides produced in early digestion are absorbed through the intestinal wall.
• D. Proteases are responsible for breaking down starches.

Correct answer: A

Rationale: The statement 'Digestion of starch begins in the mouth' is correct. Salivary amylase, an enzyme produced in the salivary glands, initiates the breakdown of starch into simpler sugars like maltose in the mouth before further digestion in the stomach. This initial breakdown of starch is crucial in the digestion of carbohydrates, marking the beginning of the digestive process. Choice B is incorrect because amylase is produced in the salivary glands, not the stomach. Choice C is incorrect because di- and tri-saccharides are further broken down into monosaccharides before absorption. Choice D is incorrect because proteases are enzymes that break down proteins, not starches.
