In the question below choose the word(s) or phrase(s) which best fills(s) the gap(s):
_____ i know, nobody has seen any loepards in this area
Answer Details
The most suitable option to fill in the blank in this sentence is "so far as".
"So far as I know, nobody has seen any leopards in this area" means that the speaker has knowledge about the area and as far as their knowledge goes, nobody has seen any leopards there. It is a way of stating that the speaker has some information about the topic at hand, but they do not claim to have complete knowledge about it.
The other options do not fit as well in this sentence. "In as much as" implies a cause-and-effect relationship, which is not appropriate in this context. "Provided" means "if" or "on the condition that", which does not make sense in this sentence. "Even as" means "simultaneously" or "at the same time", which is also not relevant to the sentence.
