Verbal Ability - Sentence Correction - Discussion

ING used after TO but in rare cases, when ing comes that word work as a noun.

In English, the form V + -ing is called a gerund if it serves as a noun. For example, the gerund form of "run" is "running". (I like cats, I like dogs, I like running). However, not all V + ing forms are gerunds--in "I am running", "running" is another verb.

1) If the to is part of a phrasal verb or verb + preposition combination:
A phrasal verb is something like " look forward to", " confess to", etc. In this case, the "to" is part of the verb itself. Some examples are:

I am looking forward to attending the party
I am committed to supporting the Linguistics proposal on Area51
2) If the to is part of an adjective + preposition combination:
For example:

A lot of women aren't accustomed to being treated so well!
I am opposed to increasing taxes.
These look similar to the examples above, but you can tell that a word like accustomed is an adjective in this case because there is a form of the verb to be. That is, you are an adjective.

3) If the to is part of a noun + preposition combination:

For example:
His addiction to gambling has caused a lot of stress for his family.
Her great dedication to teaching inspires her students.

' 'To' is related with 'in addition' mean 'in addition to' is the phase so to is not followed by enhance.

We know infinitive is to+v1.

But not using the infinitive to.

The question puts forth the meaning: Besides enhancing reputation, the companies are sponsoring social initiatives. Here is the concept of parallelism: enhancing should be parallel with sponsoring.

Use of 'Of " is wrong in option A,

To having should be followed by enhanced, which is ruled out in option B,

Option D is wordy and wrong.

So, C is correct.

Why not option (A)?

Why can't we use "to enhance their reputation"?

Why can't we use "to enhance their reputation"?

Please explain this.

Yeah we can use in addition to enhance their reputation. But the second part of the sentence is in present continuous tense. So it is appropriate to use "in addition to enhancing".

To takes v1 not v4.
