Step 1: Understand the ArgumentPremises:
Nation X ranks 28th out of 30 nations with comparable economic development in terms of the proportion of college students who obtain science degrees.
Most of Nation X's secondary-school science teachers do not have science degrees.
An inspired and knowledgeable science teacher can excite students about science, thereby encouraging them to pursue science degrees in college.
Conclusion: The teacher concludes that the reason for the low proportion of college students getting science degrees in Nation X is because most secondary-school science teachers lack science degrees.
Step 2: Identify the TaskThe question asks for the answer choice that most accurately restates the conclusion of the teacher's argument. Your task is to find the choice that best paraphrases or captures the essence of this conclusion.
Step 3: Analyze Each Answer ChoiceLet's evaluate each option in light of the conclusion.
A. Nation X has a lower proportion of college students who get a degree in science than do most nations with comparable levels of economic development.
Analysis: This restates part of the premise, not the conclusion. It mentions the fact that Nation X ranks low in the proportion of science degrees but doesn't explain why this is the case.
Conclusion: Does not restate the conclusion.
B. Most secondary-school science teachers in Nation X lack science degrees and have trouble exciting students about science.
Analysis: This option partially addresses the issue by stating that teachers lack science degrees and may have trouble exciting students. However, it doesn’t clearly connect this to the conclusion that this is the reason for the low proportion of college students obtaining science degrees.
Conclusion: Does not fully restate the conclusion.
C. Inspired and knowledgeable secondary-school science teachers can encourage their students to get a degree in science in college.
Analysis: This is another premise, not the conclusion. It merely restates the idea that inspired and knowledgeable teachers can have a positive impact on students, but it doesn’t address the issue of why Nation X has a low proportion of students getting science degrees.
Conclusion: Does not restate the conclusion.
D. The reason that only a relatively low proportion of college students in Nation X get a degree in science is that most secondary-school science teachers there lack science degrees.
Analysis: This directly captures the teacher's conclusion. It explicitly states that the reason for the low proportion of college students obtaining science degrees in Nation X is that most secondary-school science teachers lack science degrees. This is exactly what the teacher is arguing.
Conclusion: Correct answer.
E. If more secondary-school students in Nation X would become more excited about science, more of them would eventually go on to become science teachers.
Analysis: This is a hypothetical scenario and shifts the focus away from the conclusion. It speculates about future outcomes rather than restating the current conclusion about why students are not pursuing science degrees.
Conclusion: Does not restate the conclusion.
Step 4: Conclusion
The correct answer is D. The reason that only a relatively low proportion of college students in Nation X get a degree in science is that most secondary-school science teachers there lack science degrees.
Why? This choice directly captures the teacher's conclusion by linking the low proportion of science degrees among college students to the fact that most secondary-school science teachers do not have science degrees. This is the essence of the teacher's argument and is the best paraphrasing of the conclusion.
Key Takeaways for Similar Questions:
Identify the conclusion: Always pinpoint the conclusion of the argument before considering the answer choices.
Look for paraphrasing: In questions that ask you to restate a conclusion, find the choice that best paraphrases the argument's conclusion without introducing new ideas or premises.
Eliminate premises: Be careful not to confuse premises with conclusions. The conclusion should be the statement that the argument is trying to prove, based on the premises.
