Sentence Correction: Preposition and Idiom Questions - Overview

Although unacknowledged in popular memory, Luis de Santángel, finance minister to Ferdinand II, contributed his personal funds to help finance Christopher Columbus' expedition and persuaded Queen Isabella to sponsor the explorer's mission to convert Asia to Christianity.

Incorrect.

This answer choice is stylistically flawed. The original sentence uses the parallelism Luis de Santángel ... (a) contribtued ... and (b) persuaded ... . This answer choice adds the pronoun he, changing the construction to (a) Luis de Santángel ... contributed ... and (b) he persuaded ... .While this is grammatically correct, this addition is unnecessary and redundant.

Incorrect.

This answer choice is grammatically incorrect. The construction A and B (contributed...and persuading) requires that A and B belong to the same part of speech. However, in this case, A (contributed) is a conjugated verb, whereas B (persuading) is a non-conjugated verb.

In addition, the phrase persuading that Queen Isabella should is non-idiomatic. The correct idiom is persuade <someone> to <verb>.

Incorrect.

This answer choice is grammatically incorrect. The construction A and B (contributed...and persuading) requires that A and B belong to the same part of speech. However, in this case, A (contributed) is a conjugated verb, whereas B (persuading) is a non-conjugated verb.

[[snippet]]

In addition, the phrase persuading of Queen Isabella to sponsor is non-idiomatic. The correct idiom is persuade <someone> to <verb> - no preposition is needed after persuade.

Incorrect.

This answer choice is grammatically incorrect. The phrase persuaded Queen Isabella in sponsoring is non-idiomatic. The correct idiom is persuade <someone> to <verb>.

Well done!

This answer choice makes correct use of the parallel construction A and B (contributed and persuaded). It also makes correct use of the idiom persuade <someone> to <verb>.
