Answer:
When we correct the misplaced modifier, the sentence becomes:
"Using binoculars, we saw three lion cubs."
Explanation:
We can define modifiers as words or phrases which modify another word in a sentence, that is, which give information about that word. A misplaced modifier is one that is placed incorrectly in a sentence, changing its meaning or causing ambiguity.
In the sentence we are analyzing here, the position of "using binoculars" makes it sound as if the lion cubs were the ones using the binoculars. This is a clear case of misplaced modifier, and all we need to do to correct it is place the modifier closer to the word it refers to, which is "we":
"Using binoculars, we saw three lion cubs."
