Hi Folks,
Hope this article helped you. Now here comes the detailed explanation of the exercise question:
Although Google has launched ‘unchic’ glasses with a computer processor, a battery, and a tiny screen to provide Internet access through wearable technology,
it has approached Warby Parker, an e-commerce eyeglass company, to help it for designing more fashionable frames
Meaning Analysis• This sentence presents contrast.
• Google has launched glasses – wearable technology that provides internet access
o These glasses contain a computer processor, a battery, and a tiny screen.

• Even though Google has LAUNCHED these glasses, it has approached Warby Parker so that Warby Parker can help it design more fashionable frames.
o Warby Parker is an online eyeglass company.
Errors in Original Sentence• Clause 1: Although Google has launched ‘unchic’ glasses with a computer processor, a battery, and a tiny screen to provide Internet access through wearable technology,
• Clause 2: it has approached Warby Parker, an e-commerce eyeglass company, to help it for designing more fashionable frames.
1. Use of “for designing” is not grammatical. The correct expression is “help it design…”.
PoE: A. it has approached Warby Parker, an e-commerce eyeglass company, to help it for designing:
Incorrect. Error - Incorrect for the reason stated above.
B. Warby Parker, an e-commerce eyeglass company, has been approached so that it can design:
Incorrect.Error 1 – The active voice verb of Clause 2 has been turned into passive voice here. Because of this change, the choice now fails to say that Google approached Warby Parker. It just says that Warby Parker was approached but the information regarding who approached Parker is missing.
Error 2 – The original sentence says that Google approached Warby Parker to help Google design more fashionable frames. However, this choice says that Warby Parker was approached not to help Google design the frames but “to design” frames, i.e Warby will now be designing the frames. This is a clear shift in meaning.
C. it has approached Warby Parker, an e-commerce eyeglass company, to design:
Incorrect.Error 1 – This choice repeats the same meaning error as in Choice B.
D. Warby Parker, an e-commerce eyeglass company, has been approached to design:
Incorrect.Error – This choice repeats both the errors of choice B.
E. it has approached Warby Parker, an e-commerce eyeglass company, to help it design:
Correct.This choice corrects the error of choice A.
Takeaways1. The correct answer choice must contain all the information presented in the original sentence. (Refer to our new article that deals with this topic in detail – link…)
2. Omission of some words may lead to change in the meaning of the sentence. Be wary of such choices.
Hooe this helps.

Thanks.
