Consider the following sentence: “Hovering over a word produces a pop-up dictionary” (l.15-16):

I. ‘Hovering over’ means “to put the cursor on computer screen in a particular place without clicking on it”.

II. ‘pop-up dictionary’ is a dictionary that predicts when you don’t know a word.

III. ‘produces’ could be changed for ‘shows’ without altering the meaning of the sentence.

Which ones are INCORRECT?
