Read the paragraph and answer the question that follows:

the town of belmond, iowa, needs to add weather sirens. the loud and steady wail would warn citizens of approaching danger. if past history is an indication, the sirens will save hundreds of lives. with a prediction of a deadly storm season, the alert system is needed immediately.

which sentence should be revised to eliminate redundancy?

1. the town of belmond, iowa, needs to add weather sirens.
2.the loud and steady wail would warn citizens of approaching danger.
3.if past history is an indication, the sirens will save hundreds of lives.
4. with a prediction of a deadly storm season, the alert system is needed immediately.

2) The sentence which should be revised to eliminate redundancy is With a prediction of a deadly storm season, the alert system is needed immediately. A redundancy in a sentence is when something is repeated for no reason, when there is obvious detail that brings no sense and can be omitted. From the first sentence we know that   sirens were needed, so there is no need to repeat that. 

Explanation:

If past history is an indication, the sirens will save hundreds of lives.

The purpose and importance of the weather sirens are already stated in the first two sentences. The last sentence discusses the advantage of its usage in proper timing. The idea in the third sentence must be restated to make it viable.
