Question 3 of 5
What is the best summary of the passage?
Correct Answer: C
Rationale: The correct answer is C because it accurately summarizes the key points of the passage about the ECG. It mentions that the ECG measures the stages of the 'wave of excitation' within the heart and its three distinct steps. It also describes how this wave spreads from the SA node to the AV node. Choice A is incorrect because it focuses on electrostatic charges set off by the heart, which is not the main focus of the passage. Choice B is incorrect because it talks about unique electric currents on the surface of the body, which is not the main purpose of the ECG as mentioned in the passage. Choice D is incorrect because it only mentions that the ECG measures electric currents within the body without providing the specifics of the wave of excitation and its stages as described in the passage.
Question 4 of 5
What is the meaning of the word 'pathogens' as it is used in the first paragraph?
Correct Answer: C
Rationale: The correct answer is C: disease-causing substances. In the first paragraph, pathogens are referred to as agents capable of causing disease. The term 'pathogens' specifically encompasses various microorganisms like bacteria, viruses, fungi, and parasites that can infect a host and lead to illnesses. Choice A, diseases, is incorrect as pathogens are the causative agents of diseases. Choice B, vaccines, is incorrect as vaccines are used to prevent diseases caused by pathogens. Choice D, foods, is also incorrect as pathogens are not related to foods but are rather disease-causing agents. Thus, the most appropriate interpretation of 'pathogens' in the context of the paragraph is disease-causing substances.
Question 5 of 5
What is the meaning of the word 'enlist' as it is used in the second paragraph?

This is evident from the sentence mentioning individuals joining the army. Choice B, write down, is incorrect because 'enlist' doesn't refer to simply writing something. Choice C, send away, is incorrect as it implies the opposite meaning of 'enlist.' Choice D, put across, is also incorrect as it does not capture the idea of joining or signing up as 'enlist' does.
