This may be a good question to thoroughly go through regarding the potential usage of IT.

Hi,
why is the the antecedent of “it” is unclear.in A. I thought the whole thing before" it" is the antecedent

Questions :The CFO's detailed analysis of the twenty-three years of this technology firm clearly established that, for every dollar invested in research and development, including experimental research that is not initially linked with any product, it caused the firm to gain nearly six dollars in profits from sales over the next seven years.

The pronouns ‘it’ or ‘which’ usually refer to nouns, not clauses. ‘It’ can act as a placeholder such as ‘It is raining.’

In the sentence given by you, after ‘established that’ you are looking for a clause - a subject and a verb.

for every dollar invested in research and development, … , it caused the firm to gain nearly six dollars in profits

What is ‘it’? What caused the firm to gain $6? Every dollar invested…
Then why do we need the pronoun? The clause mentions ‘every dollar’ for the first time. We use pronouns when we need to re-mention the noun.

There are multiple ways of correcting it.

For every dollar…, the firm gained nearly…
(Clean, active voice)

Or
For every dollar invested…, six dollars were gained …

Or
Every dollar invested … caused the firm to gain….

Would you say: For my brother, he considers my dad his hero?

Or would you say: My brother considers my dad his hero?

Why would you use a pronoun?
