The constitutional guarantee for free Speech may have been targeted at protecting native Speakers of English from censorship, but it is not a great _____to interpret it as protecting the right to express oneself in any natural language or dialect.
It was intended for one thing but in fact it did more than that so it is not a great extrapolation or exaggeration to say that it as protecting the right to express oneself in any natural language or dialect.
So B

Please let me know where my thought process went wrong:



Here, I eliminated all options but A and B. Choosing either could show the speaker's bias. For an example, if the speaker says "enigma", it means " <X> was designed for something, but it is not confusing to see it as it had been designed to do sth else". If the speaker says "extension", then it sounds like an opinion. For e.g. "<X> was designed for something, but it is not a good idea to extend it to other uses". In this respect, considering that GRE questions are as unbiased as possible, I chose enigma. Please let me know where I went wrong.

First of all , this is not an official question as far as I do know.

Secondly, the fact that ETS makes its question aseptic for gender, race, minority and so forth is irrelevant. here is the logic that reigns supreme. The unbiased of the question is just a prerequisite of the same NOT a way the craft the question itself to make it more tricky or not!!
