Explanatory AnswerStep 1 of solving this GMAT Sentence Correction Question: Identifying What Is Tested
Look for differences across the answer options to identify what is being tested in the sentence.
Some of the options use the plural verb “have succeeded” and some use the singular construction “has succeeded”.
Some options use the construction “in buying and leasing” and some use the “to buy and lease” construction.
Also, the placement of the word “once” varies across the options.
Step 2 of solving this GMAT Sentence Correction Question: Understanding the Sentence
The subject of the sentence is “German luxury brands”, which is plural. Therefore, the corresponding plural verb should be “have succeeded”.
It is idiomatic to say “in getting x... to do y”. The correct construction should be “in getting people… to buy and lease”.
The word “once” should always be placed before the word that it has to refer to. In this sentence, “once” refers to the verb “thought”. Therefore, “have once thought” should be the correct placement.
Step 3 of solving this GMAT Sentence Correction Question: Eliminating Options
Choice (A) is incorrect because the construction “in buying” is not idiomatic.
Choice (C) can be eliminated because the adverb “once” has been misplaced.
Choices (D) and (E) can be eliminated because of the usage of the singular verb
“has succeeded”. Moreover, choice (E) can be eliminated for the construction
“in buying”.Choice B is the correct answer.
