Inhibitor is more of a discouragement (you may recall them in chemistry or mathematical biology), while forbidden is a hard-block. This is what I’d think at least.
My take for SE questions is to always stick with Greg’s pairing strategy. This is one of those examples where it works splendidly as I didn’t even have to read the Sentence to select my final answer.
Hope you are familiar with it, else you can check his lecture in the Verbal section.
So basically, I just looked for pairs and the only one I could find was Bridling and Inhibiting. Which are the closest to being a pair, as Bridling means to control or restrain something and Inhibiting means to stop or curb something. Forbidding doesn’t have a pair as its an extreme word, provoking is also not having a pair though one might like to pair it with exciting but its all about being Binary here. All the other words are non-pairs and so A and D have to be the right answer.
Free advice: To be honest I like this approach because we tend to convince ourselves why certain words make sense in the context, but as Greg said in one of his classes, we have to find the closest pair and not the best answer. Because trying to find the best answer can lead you to trouble and you will end up justifying your ‘story’ as to why two words are pairs when they are not in reality. Be binary while doing SE, it will surely help.
To one extreme extent, sure. It could be inferred as a way of completely prohibiting something however, we have to look into this nuance based on the context as well. What fits? Is it with an essence of curbing/retraining something or completely banning the kind of frequent casual use of web sites? I’m inclined to chose the former, what about you?
I suppose, the meaning of the sentence will help you decide on the final step. Do you agree?
I definitely see how this question feels very subjective and how this looks like a trick question. Hope such a question doesn’t come in the test lol.
