2. What does the word 'suit' mean in the passage about Bridge?

A. A set of clothing to be worn together.
B. Any of the four sets into which a deck of cards is divided.
C. To request or appeal persistently.
D. To be convenient or right for.

Correct answer: B

Rationale: The correct answer is B: 'Any of the four sets into which a deck of cards is divided.' In the context of card games like Bridge, 'suit' refers to one of the four divisions of a deck of cards - spades, hearts, diamonds, or clubs. Each suit contains cards of different ranks, and during the game, players must follow suit if possible, meaning they must play a card of the same suit that was led. This is crucial for understanding card hierarchy and gameplay in Bridge. Choice A is incorrect because it defines 'suit' in terms of clothing, which is not relevant to the context of the passage. Choice C is incorrect as it defines 'suit' as a verb meaning to request persistently, which is unrelated to the card game. Choice D is also incorrect as it defines 'suit' as an adjective meaning to be convenient or right for, which is not the meaning intended in the passage about Bridge.

3. Which statement is not listed as a detail within the passage?

A. Changes in the ECG are typically used for the diagnosis of abnormal cardiac rhythm.
B. The signal has a characteristic record called the electrocardiogram.
C. The 'wave of excitation' starts at the SA node.
D. The 'wave of excitation' spreads through the heart wall and is accompanied by electric changes.

Correct answer: A

Rationale: The corrected statement should be: Changes in the ECG are not typically used for the diagnosis of abnormal cardiac rhythm. The passage mentions that the heart sends out electric currents in waves, and the 'wave of excitation' spreads through the heart wall accompanied by electric changes. It details the process of how the heart's electric impulses are recorded and how abnormalities can be detected. However, it does not state that ECG changes are specifically used for diagnosing abnormal cardiac rhythms. Choice A is the correct answer because it misrepresents the information provided in the passage. Choices B, C, and D are all supported by the passage and align with the details mentioned regarding the electrocardiogram and the wave of excitation in the heart.

5. What is the meaning of the word respite as used in the first paragraph?

A. Relief
B. Treatment
C. Guardian
D. Specialist

Correct answer: A

Rationale: In this context, 'respite' refers to relief, providing caregivers with temporary rest or a break from their caregiving duties. The word 'respite' is associated with giving caregivers a brief period of relief, not with treatment, guardianship, or specialization. The extract mentions 'respite services' along with caregiver services, indicating that respite is a form of support or relief for caregivers.
