Official Solution:
To curb potential fraud, a proposed law would require citizens to bring photo ID to polling places when they vote.
A. To curb potential fraud, a proposed law would require citizens to bring photo ID to polling places when they vote.
B. A proposed law would require citizens to bring photo ID to polling places when they vote to curb potential fraud.
C. A proposed law will require citizens to curb potential fraud by bringing photo ID to polling places when they vote.
D. A proposed law will curb potential fraud by requiring citizens to vote at polling places with photo ID.
E. To curb potential fraud, a proposed law requires citizens to bring photo ID to polling places when they vote.
A. CORRECT. The sentence correctly depicts that photo ID is required to be brought to polling places to curb fraud during voting.
B. The intended meaning of the sentence is that photo ID is required to be brought to polling places to curb fraud during voting. However this option distorts the meaning, implying that the purpose of the voting is to curb fraud.
C. There are a few issues here. "Will require" is a little bit too certain, since the law has only been proposed; "would" is better. It's a little bit of a stretch to say that citizens "curb potential fraud by bringing photo ID to polling places," but that's not necessarily wrong -- it just makes more sense to say that the law curbs fraud by requiring ID, as in answer choice (B). And "they" is a little bit further from "citizens" than we'd ideally like.
There's no single factor that makes C DEFINITELY wrong, but there's enough goofiness here to make it an inferior choice to A.
D. This phrase “polling places with photo ID” wrongly indicates that the polling places have photo IDs.
E. Using the simple present tense for the verb "requires" is wrong, since the law has not taken effect yet. "They" is also arguably a bit ambiguous.
