To solve this question, let us deploy
IMS's four-step technique.
STEP #1 ->
IDENTIFY THE QUESTION TYPELet us read the question stem to identify the question type.
Quote:
Which of the following, if true, most seriously weakens the argument?
The stem indicates a
weakening question.
STEP #2 ->
X-RAY THE ARGUMENTIn a
weakening question, it is a must to x-ray the argument and deconstruct it by figuring out the conclusion and the premise. Let us therefore read the argument first and deconstruct it soon after.
Quote:
A jewellery manufacturer produces rings in two metals—gold and platinum. The manufacturer has noted that, over the last three years, the gold rings have consistently outsold the platinum ones by a large margin, even though the designs available in both the metals are exactly the same. This has led the manufacturer to conclude that consumers prefer gold to platinum.
CONCLUSION: Consumers prefer gold to platinum.
PREMISE: Over the last three years, the gold rings have consistently outsold the platinum ones by a large margin, even though the designs available in both the metals are exactly the same.
STEP #3 ->
FRAME A SHADOW ANSWERTo frame a shadow answer, we must know what the correct answer should do. In this question, the correct answer must weaken the argument; a great way to weaken this argument would be to cast doubt on its conclusion.
SHADOW ANSWER: Any situation that leads us to believe that consumers do not necessarily prefer gold to platinum despite the fact that gold rings, which have the same designs as the platinum rings, have consistently outsold platinum rings by a large margin.
STEP #4 ->
ELIMINATE INCORRECT ANSWERSOptions that do not match the shadow answer can be eliminated.
(A)
Over the last three years, diamond rings have outsold both gold and platinum ones. |
NOT A MATCH |
This option discusses diamond rings; however, the argument does not concern itself with diamond rings in the first place. Therefore, even if what is stated in this option were to be true, we would still not have a reason to believe that consumers do not necessarily prefer gold to platinum. |
ELIMINATE(B)
Jewellery buyers give more importance to design than to the metal used. |
NOT A MATCH |
If jewellery buyers actually give more importance to design than to the metal used, they may opt for either gold or platinum since rings made of both metals have the same designs; this option therefore definitely does not lead us to believe that consumers do not necessarily prefer gold to platinum. |
ELIMINATE(C)
Platinum is easier to maintain than is gold. |
NOT A MATCH |
If platinum is easier to maintain than gold, consumers should go for platinum; however, we know that consumers have tended to buy more gold rings than platinum ones. Remember, we need an option that leads us to believe that consumers do not necessarily prefer gold to platinum DESPITE THE FACT THAT gold rings, which have the same designs as the platinum rings, have consistently outsold platinum rings by a large margin. If anything, this option strengthens the author's conclusion by making us believe that customers actually prefer gold to platinum despite the fact that the former is not as easy to maintain as the latter. |
ELIMINATE(D)
Platinum rings take longer to produce than do gold rings. |
NOT A MATCH |
If platinum rings do take longer to produce than do gold rings, do we have a reason to believe that consumers do not necessarily prefer gold to platinum? Of course not! The time taken to produce rings has got nothing to do with the preference of people. |
ELIMINATE(E)
Gold rings cost considerably less than do platinum ones. |
MATCHES THE SHADOW ANSWER |
Bingo! This option tells us that gold rings have outsold platinum ones not because people prefer gold over platinum but because gold rings cost CONSIDERABLY less than do platinum ones. This option clearly does exactly what we want the correct answer to do! |
MARK AND MOVEThus, (E) has to be the correct answer.
