My attempt at explaining D:
- Identify the type of question:
Strengthen- Most, if not all Strengthen questions require the test taker to strengthen the
Conclusion- Identify the Conclusion: "
Current farm policy is institutionalized penalization of consumers."
- Therefore, any answer choice that lends support to this conclusion is a
StrengthenerI. This is the easiest answer choice - clearly consumers are penalized by higher food prices. This answer provides cold, hard numbers (i.e., $12 bn).
YESII. This is the trickiest answer choice - the test maker tries to throw you off by shifting your focus away from the conclusion and onto the premise. This is why for CR questions, identifying and separating the conclusion and premise (in addition to subsidiary conclusion and counter-premise) is so important. The trick is to not fall into the trap of trying to strengthen the premise (i.e., the second sentence of the stimulus). At the end of the day, you are trying to prove the conclusion that
[general] farm policy hurts consumers. Regardless of whether this answer choice pertains to food prices, this answer choice gives readers more reason to believe the conclusion.
YESIII. Also pretty easy to get rid of this answer - a farmer's net worth has nothing to do with whether farm policy penalizes consumers. The focus of the conclusion is on consumers, not farmers.
NO
