Sentence Correction: Dangling Modifiers - Overview

Basing their opinion on fatality rates in road accidents, British road and safety groups propose that the driving age will be increased.

This answer choice is grammatically incorrect. Propose is one of the nine verbs to which the Subjunctive rule applies (if it is followed by that). This means that the next verb after propose that should be in base form. However, will be increased is not in base form.

What helps us identify this question as a Subjunctive question as well as identify the mistake is the following Stop Sign:

propose/recommend/require/request/insist/suggest/mandate/ask/demand that

Whenever you come across this Stop Sign, make sure that the following verb is in its base form.

This answer choice is grammatically incorrect and repeats the original Subjunctive error. Propose is one of the nine verbs to which the Subjunctive rule applies (if it is followed by that). This means that the next verb after propose that should be in base form. However, increases is not in base form.

What helps us identify this question as a Subjunctive question as well as identify the mistake is the following Stop Sign:

propose/recommend/require/request/insist/suggest/mandate/ask/demand that

Whenever you come across this Stop Sign, make sure that the following verb is in its base form.

This answer choice is grammatically incorrect and repeats the original Subjunctive error. Propose is one of the nine verbs to which the Subjunctive rule applies (if it is followed by that). This means that the next verb after propose that should be in base form. However, has been increased is not in base form.

What helps us identify this question as a Subjunctive question as well as identify the mistake is the following Stop Sign:

propose/recommend/require/request/insist/suggest/mandate/ask/demand that

Whenever you come across this Stop Sign, make sure that the following verb is in its base form.

Although this answer choice corrects the original Subjunctive error by not using the Subjunctive form, it creates a Dangling Modifier. The original sentence begins with a modifier: Basing their opinion on fatality rates in road accidents. A modifier should be placed right next to the noun it describes. The only noun that this modifier can logically modify is British road and safety groups. However, what immediately follows the modifier is an increase and an increase cannot have an opinion.

What helps us identify this question as a Dangling Modifier question as well as identify the mistake is the following Stop Sign:

A modifier, characterized by all of the following:
1. Verb+ing or Verb in 3rd form
2. Separated from the rest of the sentence by a comma
3. Appears at the very beginning of the sentence

Whenever you see this Stop Sign, focus on the modifier: check whether the noun right after the modifier is indeed the noun that the modifier describes. If it isn't - you've found your mistake.

Very well done!

This answer choice follows the Subjunctive rule by placing the base form verb be after the phrase propose that.
