Choose the most suitable option to replace the highlighted part of the sentence: He speaks as if he was knowing everything.
as if he knew everything
The clause "as if he was knowing everything" has two faults: "know" is a stative verb and is not normally used in the continuous ("was knowing"), and after "as if" we use the past subjunctive to express something unreal or contrary to fact.
Because he does not really know everything, the unreal comparison after "as if" takes the simple past form "knew". This gives the correct expression "as if he knew everything".
"As if he knows everything" uses the present tense, which treats the situation as real rather than hypothetical. "As though he knew everything" is grammatically fine in itself, but it replaces the connector "as if" with "as though", changing more of the highlighted part than needed; the question asks for the most suitable replacement keeping "as if". "As he knows everything" drops "if" altogether and changes the meaning to a reason.
Hence, the most suitable replacement is "as if he knew everything".
