Emit: 1. (verb) to produce, to voice omit: 1. (verb) to leave something out, to forget which sentence contains correct word usage? the alarms omit a frequency that cannot be heard by the human ear. the teacher will omit the lowest score in order to increase the averages. we are attempting to emit the last few chapters in order to save paper. the movie emitted the offensive graphics that caused the boycott.

The answer is the second option. I hope this helps

The correct answer is sentence 2 - The teacher will omit the lowest score in order to increase the averages.

Like the definitions already explained, to emit means to produce something, whereas to omit means to leave something out. Now, let's go through all sentences:

Sentence 1 - instead of omit, it should say emit (to emit a frequency means to produce it)

Sentence 3 - instead of emit, it should say omit (to omit chapters means to leave them out)

Sentence 4 - instead of emitted, it should say omitted (to delete the offensive graphics)

Sentence 2 is correct because the teacher wants to leave out the lowest scores so as to increase the averages; he doesn't want to produce them - that would be quite the opposite of what he is trying to do.
