General: The commander of the Air Force has recommended that we deploy the G28 aircraft in the reconnaissance mission, because the G28 can fly lower to the ground without being detected and could therefore retrieve the necessary information more efficiently than the currently stationed D12. But the D12 is already in the area and poised for takeoff, and would have just enough time to accomplish the mission if deployed immediately, while the G28 would require four days just to arrive in the area and get outfitted for the mission. Since the mission's deadline is immovable, I am forced to overrule the commander's recommendation and order the deployment of the D12.

Which of the following is assumed in the general's argument?


(A) The quality of information retrieved from the mission would be higher if the D12 were deployed than if the G28 were deployed.

(B) By the time the G28 arrived in the area and was outfitted for the mission, the D12 would have already completed the mission if deployed immediately.

(C) The ability of an aircraft to fly low to the ground is not a significant consideration when choosing aircraft for a reconnaissance mission.

(D) It would take longer for any aircraft not currently in the area besides the G28 to arrive in the area and get outfitted for the mission.

(E) Any time saved during the mission due to the operation of the more efficient G28 would not offset the additional time required to deploy the G28.

General: The commander of the Air Force has recommended that we deploy the G28 aircraft in the reconnaissance mission, because the G28 can fly lower to the ground without being detected and could therefore retrieve the necessary information more efficiently than the currently stationed D12. But the D12 is already in the area and poised for takeoff, and would have just enough time to accomplish the mission if deployed immediately, while the G28 would require four days just to arrive in the area and get outfitted for the mission. Since the mission's deadline is immovable, I am forced to overrule the commander's recommendation and order the deployment of the D12.

Which of the following is assumed in the general's argument?

Since C and E are close to be correct, let's look at each of these.

(C) The ability of an aircraft to fly low to the ground is not a significant consideration when choosing aircraft for a reconnaissance mission.
It is possible that D12 also flies low to the ground. G28 just flies lower. Thus, we can rule this out.

(E) Any time saved during the mission due to the operation of the more efficient G28 would not offset the additional time required to deploy the G28.
This is the required assumption.
Conclusion: The General is forced to deploy D12 rather than G28 because of time issues.
Imagine that D12 is deployed today and it takes D12 10 days to finish the mission. Now imagine we deploy G28, we are lagging by 4 to 5 days.What if G28, being more efficient, completes the mission in 3 days. In that case the mission gets completed in 8 days; time taken is lesser that that taken by D12.

(A) The quality of information retrieved from the mission would be higher if the D12 were deployed than if the G28 were deployed. --> Irrelevant

(B) By the time the G28 arrived in the area and was outfitted for the mission, the D12 would have already completed the mission if deployed immediately. --> Incorrect, it talks about the chances that D12 might complete the mission before time, that way we can also state G28 might complete it before time or beyond the deadline, its all about probability, we can not bet on any of the chances

(C) The ability of an aircraft to fly low to the ground is not a significant consideration when choosing aircraft for a reconnaissance mission. --> Out of scope

(D) It would take longer for any aircraft not currently in the area besides the G28 to arrive in the area and get outfitted for the mission. --> Irrelevant

(E) Any time saved during the mission due to the operation of the more efficient G28 would not offset the additional time required to deploy the G28. --> Correct, it mentions the assumption that any time saved during operation can not compensate late deployment

Hence, E.

IMO E
If we negate the option E, the conclusion will be weakened. Hence, in order to choose the right option for an assumption question, negating the answer options works the best.

General: The commander of the Air Force has recommended that we deploy the G28 aircraft in the reconnaissance mission, because the G28 can fly lower to the ground without being detected and could therefore retrieve the necessary information more efficiently than the currently stationed D12.

Since the mission's deadline is immovable, I am forced to overrule the commander's recommendation and order the deployment of the D12.
Deadline= Time taken for deployment + Time taken for finishing the work provided.
So, if time taken for deployment is more and time taken for finishing the work is also more then it is difficult to complete the work within given time frame.
But, if time taken for deployment is more but time taken to complete the work is very less then work would be completed before time.
So, combination of these two facts will help us solving this particular question.

Which of the following is assumed in the general's argument?


(A) The quality of information retrieved from the mission would be higher if the D12 were deployed than if the G28 were deployed.
// This could be wrong because it is already given that quality of information provided by G28 is good//

(B) By the time the G28 arrived in the area and was outfitted for the mission, the D12 would have already completed the mission if deployed immediately.// But this don't helps us to determine whether we should deploy G28 or not//

(C) The ability of an aircraft to fly low to the ground is not a significant consideration when choosing aircraft for a reconnaissance mission.// Out of scope//

(D) It would take longer for any aircraft not currently in the area besides the G28 to arrive in the area and get outfitted for the mission.// Out of scope //

(E) Any time saved during the mission due to the operation of the more efficient G28 would not offset the additional time required to deploy the G28.// Correct option: Follows the facts stated above and on negating this alters the conclusion//

Hope this helps...

KAPLAN OFFICIAL EXPLANATION:



Next up we have "Critical Reasoning meets Top Gun." The general is trying to determine which of two types of aircraft would better fit the needs of the Air Force for an upcoming mission, and there are a number of logical elements present here. While the commander of the Air Force prefers the G28 because it could perform the necessary task more efficiently, the general orders that the D12 be used instead. He provides one piece of evidence to support this decision: Only the D12 can perform the task in time to meet the mission's deadline. When an author argues for one option over another, the author must assume that the benefit provided by the preferred option can only be found in that option. In other words, the author must assume that the G28 would not fulfill the mission in the allotted period of time. But perhaps there's an alternative? The general says that it would take four days for the G28 to be ready for the mission, but he never explicitly says that the G28 couldn't meet the deadline. Perhaps the plane's greater efficiency would enable it to still complete the mission in the allotted period of time, despite the later start. That's a plausible alternative that the general has overlooked. In order for the general's conclusion to be valid, he must assume that the G28 could not perform the mission by the immovable deadline. Thus he assumes that the G28's efficiency would not recoup the extra time that it would take for the G28 to begin the mission. (E) is the answer.

The number issue is a common one: The test makers like to create situations in which a decrease in one area is made up, in fact, even surpassed, by an increase in something else. And one could see this scenario in terms of a scope shift, as well: The general speaks of the efficiency of the G28 early on, but then makes his recommendation based solely on the time factor. Recognizing that shift is key to understanding the assumption here.

An 800 test taker has the ability to see situations in Critical Reasoning questions from a number of angles, and to think through problems on a number of different levels. The more tools in your test-day arsenal, the better.

(A) The stimulus never states that one aircraft retrieves higher quality information than the other; one is simply more efficient. So (A) is not relevant to the general's decision.

(B) goes too far. The author never states how long the mission would take, so there's no basis for assuming that the D12 would be done before the G28 arrived.

(C) The ability to fly low to the ground is a significant consideration to the commander, and the general never contests the importance of this consideration. He just overrides it by making the deadline a more significant consideration, so he need not assume (C) in order to formulate his recommendation.

(D) focuses on aircraft other than the G28. Aren't two enough to deal with? The author seems to think so, because he discusses only the D12 and the G28. How long it would take other kinds of planes to get to the scene is irrelevant to the general's argument, which specifically deals with a choice between these two.
