Paint on a new airliner is usually applied in two stages: first, a coat of primer, and then a top coat. A new process requires no primer, but instead uses two layers of the same newly developed coating, with each layer of the new coating having the same thickness and weight as a traditional top coat. Using the new process instead of the old process increases the price of a new aircraft considerably.

Which of the following, if true, most strongly indicates that it is in an airline's long-term economic interest to purchase new airliners painted using the new process rather than the old process?

(A) Although most new airliners are still painted using the old process, aircraft manufacturers now offer a purchaser of any new airliner the option of having it painted using the new process instead.
(B) A layer of primer on an airliner weighs more than a layer of the new coating would by an amount large enough to make a difference to that airliner's load-bearing capacity.
(C) A single layer of the new coating provides the aluminum skin of the airliner with less protection against corrosion than does a layer of primer of the usual thickness.
(D) Unlike the old process, the new process was originally invented for use on spacecraft, which are subject to extremes of temperature to which airliners are never exposed.
(E) Because the new coating has a viscosity similar to that of a traditional top coat, aircraft manufacturers can apply it using the same equipment as is used for a traditional top coat.

Can someone please provide a detailed explanation for this question. Thanks!

Hi,

In this questions you want to strengthen the idea that the new coating will be beneficial financially in the long run even though it is much more expensive initially. So the answer will provide some financial benefit that could outweigh the initial extra cost.

Paint on a new airliner is usually applied in two stages: first, a coat of primer, and then a top coat. A new process requires no primer, but instead uses two layers of the same newly developed coating, with each layer of the new coating having the same thickness and weight as a traditional top coat. Using the new process instead of the old process increases the price of a new aircraft considerably.

Which of the following, if true, most strongly indicates that it is in an airline's long-term economic interest to purchase new airliners painted using the new process rather than the old process?

(A) Although most new airliners are still painted using the old process, aircraft manufacturers now offer a purchaser of any new airliner the option of having it painted using the new process instead.
No financial benefit
(B) A layer of primer on an airliner weighs more than a layer of the new coating would by an amount large enough to make a difference to that airliner's load-bearing capacity.
The plane will be able to carry more with the new coating and therefore make more money per flight. CORRECT
(C) A single layer of the new coating provides the aluminum skin of the airliner with less protection against corrosion than does a layer of primer of the usual thickness.
This only addresses a single layer. There will be two layers. So this is irrelevant.
(D) Unlike the old process, the new process was originally invented for use on spacecraft, which are subject to extremes of temperature to which airliners are never exposed.
(E) Because the new coating has a viscosity similar to that of a traditional top coat, aircraft manufacturers can apply it using the same equipment as is used for a traditional top coat.
This is saying that you won't have to buy new equipment to put on the coating BUT it does not address any new financial benefit to offset the costs.

Let me know if you need more advice on this questions. Happy Studies.

Hi fozzzy,

This is "Evaluate a Plan" type question. The keywords in the question is "long term" and "economic interest", so the correct answer choice will provide a strong economic incentive for the airliner to use the new painting process.

Stimulus says that the new process increases the price of the new aircraft considerably. So, there should be something that could offset this price and increase the revenue in long term
.

(A) Although most new airliners are still painted using the old process, aircraft manufacturers now offer a purchaser of any new airliner the option of having it painted using the new process instead.

The aircraft manufacturer offers an option, but this will not offset the price of new painting process.

(B) A layer of primer on an airliner weighs more than a layer of the new coating would by an amount large enough to make a difference to that airliner's load-bearing capacity.

The key here is "load-bearing capacity". If the airliner's load-baring capacity increases then it can carry more luggage/ passengers etc, this in turn would generate greater revenue for the airliner. This choice most strongly indicates that switching to the aircraft with the new paint will be in the long-term economic interest for the airliner
(C) A single layer of the new coating provides the aluminum skin of the airliner with less protection against corrosion than does a layer of primer of the usual thickness.

This choice discusses about a "single layer" but the new process will include "two layers" of coating. So, this choice is will not help us determine whether the new painting process will be in the economic interest of the airline.

(D) Unlike the old process, the new process was originally invented for use on spacecraft, which are subject to extremes of temperature to which airliners are never exposed.

The stimulus discusses aircraft; the performance of new painting process on spacecraft makes a wrong comparison. It could be possible that the aircraft will never face extreme temperature.

(E) Because the new coating has a viscosity similar to that of a traditional top coat, aircraft manufacturers can apply it using the same equipment as is used for a traditional top coat.

Even if the aircraft manufacturers are using the same equipment, it doesn't mean that they will sell the aircraft cheap enough so that the airline can have an economic advantage.

Hope that helps,

Vercules

Do you have any tips on how to tackle Evaluate a plan question stems effectively?

Hi,

e-GMAT had recently written an article on the approach to handle Evaluate questions. You may find it useful. Here's the link:
