Stimulus Summary
Economic growth → Consumer confidence balanced with small amount of skepticism
Answer Anticipation
Principle (Must be True) questions present a principle in the stimulus (usually a conditional; frequently two conditionals) and ask you to find an answer that establishes the sufficient condition and concludes the necessary condition. You should make sure that the judgment/conclusion-sounding condition is in the necessary condition.
Here, the principle’s necessary condition arguably could be a conclusion, but so could the sufficient, so let’s take the contrapositive just to be ready for that eventuality:
~Confidence balanced with small amt of skepticism → ~Econ growth
Now, let’s find an answer that lines up with either of these!
Answer choices
-
AAny nation in which Remaining source text redacted.
Why choice A is not credited
Confidence balanced with a small amt of skepticism → Econ growth. This is the reversal of the principle, so it’s incorrect. -
BAny nation in which Remaining source text redacted.
Why choice B is not credited
~Mostly skepticism → ~Econ growth. The sufficient condition for there not to be growth is that there isn’t confidence balanced with a small amount of skepticism. That’s not the same as not being mostly skeptical, as this answer states, so it’s incorrect. -
CAny nation in which Remaining source text redacted.
Why choice C is not credited
If the prevailing attitude is just confidence or skepticism, then there isn’t a balance. There not being a balance is the sufficient condition of the contrapositive, so the stimulus would allow us to conclude that there won’t be economic growth, which isn’t what this answer choice states. It is therefore incorrect. -
DAny nation in which Remaining source text redacted.
Why choice D matches the stem
If the prevailing attitude is just confidence, then there isn’t a balance. There not being a balance is the sufficient condition of the contrapositive, so the stimulus would allow us to conclude that there won’t be economic growth, as this answer choice states. Since this answer choice lines up with the contrapositive of the principle, it’s the correct answer. -
EAny nation in which Remaining source text redacted.
Why choice E is not credited
Note that this answer swaps where skepticism and confidence fall in the term - it’s a small amount of confidence that serves as a balance! That’s a shift from the stimulus, so this answer is incorrect. (Also, as in (A), it reverses the relationship in the principle.)
