1. What is the charge of noble gases?

• A. -1
• B. 0
• C. 1
• D. 2

Correct answer: B

Rationale: The correct answer is B: 0. Noble gases have a charge of 0 because they have full valence shells and are inert. This makes them stable and unreactive, resulting in a charge of 0 as they do not readily gain or lose electrons. Choices A, C, and D are incorrect because noble gases do not typically form ions by gaining or losing electrons, so they do not carry a charge of -1, 1, or 2.

2. What does 'Contour' mean?

• A. Flat area
• B. Shape or outline of something
• C. Volume of a structure
• D. Height of a structure

Correct answer: B

Rationale: The term 'Contour' specifically refers to the shape or outline of something. In art and geography, contours are used to represent the outline or shape of an object or landform, making choice B the correct definition. Choice A, 'Flat area,' is incorrect as it does not capture the essence of contour which is about the shape or outline. Choice C, 'Volume of a structure,' is unrelated to the concept of contour. Choice D, 'Height of a structure,' is also incorrect as contour is more about the shape and not the height of an object.

3. What is the meaning of the word consensus as it is used in the last paragraph about Barefoot Running?

• A. Investigation.
• B. Purpose.
• C. Trepidation.
• D. Unanimity.

Correct answer: D

Rationale: "Consensus" refers to a general agreement or unanimity among individuals, particularly regarding the safety and effectiveness of barefoot running. The passage discusses differing opinions on this subject, indicating that there is not a unanimous agreement. Thus, choice D accurately captures the meaning of "consensus" within the context of the discussion.

4. What are the three steps of the 'wave of excitation'?

• A. The discharge from the SA node, the peak ECG, and the excitement of the ventricle.
• B. The excitement of the ventricle, the relaxing of the ventricle, and the systemic neural response.
• C. The contraction of the atrium, the relaxation of the atrium, and the contraction of the ventricle.
• D. The excitation of the atrium, the excitement of the ventricle, and the relaxing of the ventricle.

Correct answer: D

Rationale: The correct steps of the 'wave of excitation' are the excitation of the atrium, excitement of the ventricle, and relaxation of the ventricle. In the described process, the 'wave of excitation' starts with the discharge from the SA node, leading to the excitation of the atrium. Next, the peak ECG corresponds to the excitement of the ventricle, not its relaxation. Finally, the wave concludes with the relaxation of the ventricle, not its contraction. Therefore, choices A, B, and C are incorrect as they do not accurately describe the sequential steps of the 'wave of excitation' as presented in the extract.

5. Select the word or phrase that makes this sentence grammatically correct: 'Felix was pleased ____ the progress he had made in his program.'

• A. among
• B. with
• C. regards
• D. besides

Correct answer: B

Rationale: The correct preposition to use in this context is 'with.' 'Felix was pleased with the progress he had made in his program' indicates that Felix's satisfaction is directly related to the progress he achieved. 'Among' is incorrect as it implies being part of a group, 'regards' is not a suitable preposition in this context, and 'besides' does not convey the intended meaning of satisfaction with the progress.
