1. Which of the following words is a synonym for 'happy'?

• A. Sad
• B. Joyful
• C. Angry
• D. Tired

Correct answer: B

Rationale: The correct answer is 'B: Joyful.' 'Joyful' is a synonym for 'happy' as both words convey feelings of pleasure, contentment, and delight. Choice 'A: Sad' is incorrect as it is an antonym of 'happy,' representing feelings of sorrow or unhappiness. 'Angry' in choice 'C' and 'Tired' in choice 'D' are also incorrect as they represent different emotional states and do not share the same meaning as 'happy.'

2. 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. The passage indicates that the world powers were already in a combustible situation due to complicated military alliances, making war extremely likely even without the assassination of Archduke Franz Ferdinand. Choice B is incorrect because the passage does not suggest that World War I would never have happened. Choice C is incorrect as it specifically names the countries that would have started the war, which is not supported by the passage. Choice D is also incorrect as the passage does not solely attribute the war's start to Austria.

3. Which muscle has involuntary cells that are branched and striated and connected by intercalated discs with gap junctions?

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

Correct answer: B

Rationale: The correct answer is B: Cardiac muscle. Cardiac muscle cells fit the description provided in the question; they are involuntary, striated, and branched, with intercalated discs containing gap junctions that allow for synchronized contractions of the heart. Smooth muscle (choice A) lacks striations and is found in the walls of internal organs. Skeletal muscle (choice C) is voluntary and attaches to bones for movement. 'Epithelial muscle' (choice D) is not a valid muscle type, making it an incorrect choice.

4. Which of the following structures is responsible for transmitting electrical impulses in the nervous system?

• A. Neuron
• B. Axon
• C. Myelin
• D. Dendrite

Correct answer: A

Rationale: The correct answer is A: Neuron. Neurons are specialized cells that transmit electrical impulses in the nervous system. While the axon is the part responsible for conducting these impulses over long distances, it is the neuron as a whole that is ultimately responsible for transmitting electrical impulses. Myelin is a fatty substance that surrounds and insulates axons, speeding up signal transmission. Dendrites, on the other hand, receive signals from other neurons. Therefore, although the axon plays a significant role in transmission, the neuron is the fundamental unit responsible for transmitting electrical impulses in the nervous system.

5. What is the term for the inflammation of the airways in the lungs, often causing wheezing and difficulty breathing?

• A. Pneumonia
• B. Emphysema
• C. Asthma
• D. Pleurisy

Correct answer: C

Rationale: Asthma is a chronic respiratory condition characterized by inflammation of the airways in the lungs, leading to symptoms such as wheezing, shortness of breath, chest tightness, and coughing. Pneumonia is an infection in the lungs caused by bacteria, viruses, or fungi, leading to symptoms like fever, cough, and difficulty breathing. Emphysema is a type of chronic obstructive pulmonary disease (COPD) characterized by damage to the air sacs in the lungs, resulting in shortness of breath and a chronic cough. Pleurisy, on the other hand, is inflammation of the lining around the lungs, causing chest pain that worsens with breathing or coughing. Therefore, the correct term for the inflammation of the airways in the lungs with symptoms of wheezing and difficulty breathing is Asthma.
