B. Prefer shrill, grating, and brassy voice
C. Have no particular reactions to different voices

Correct answer: C

Rationale: Based on the extract provided, the author discusses the effects of different voice qualities on others but does not express any preference or reaction towards specific voices. The author emphasizes the negative impact of harsh tones and provides insights into how voice qualities can influence perceptions. As a result, it can be inferred that the author has no particular reactions to different voices. Choices A and B are incorrect as there is no mention of the author's public speaking experience or preference for specific voice qualities in the passage.

C. To spread out
D. To eliminate

Correct answer: B

Rationale: The correct answer is B. 'Expand' means to increase in size or amount. Choice A, 'To decrease in size,' is the opposite of what 'expand' means. Choice C, 'To spread out,' is related to expanding but does not precisely define the term. Choice D, 'To eliminate,' is not synonymous with the term 'expand.'

3. Which organelle is responsible for making proteins?

A. Ribosome
B. Chloroplast
C. Lysosome
D. Mitochondrion

Correct answer: A

Rationale: Ribosomes are the organelles responsible for protein synthesis within the cell. They are the sites where amino acids are linked together to form proteins based on the instructions carried by mRNA (messenger RNA). Ribosomes can be found free-floating in the cytoplasm or attached to the endoplasmic reticulum, and they play a crucial role in translating genetic information into proteins. Chloroplasts are responsible for photosynthesis, lysosomes are involved in digestion and waste removal, and mitochondria are known as the powerhouse of the cell responsible for energy production through cellular respiration. Therefore, the ribosome is the correct organelle responsible for making proteins.

4. Which word is not spelled correctly in the sentence: 'The physician thought it was unnecessary to explain the procedure.'

A. physician
B. unnecessary
C. explain
D. procedure

Correct answer: B

Rationale: The word 'unnecessary' is misspelled as 'unecessary' in the sentence. The correct spelling should have double 'n' as in 'unnecessary'. Choice A, C, and D are spelled correctly in the sentence provided.

5. What is the temperature in Celsius when it is 98.6 degrees Fahrenheit?

A. 35 Celsius
B. 37 Celsius
C. 38 Celsius
D. 36.5 Celsius

Correct answer: B

Rationale: To convert 98.6 degrees Fahrenheit to Celsius, you can use the formula (98.6 - 32) × 5/9. By solving this equation, the temperature is calculated to be 37°C. Therefore, the correct answer is B, 37 Celsius. Choice A, 35 Celsius, is incorrect because it is not the outcome of the conversion formula. Choice C, 38 Celsius, is incorrect as well, as it does not match the correct conversion result. Choice D, 36.5 Celsius, is also incorrect as it does not correspond to the accurate conversion from 98.6 degrees Fahrenheit.
