Answer:
The sentence is already clear.
It sounds awkward to split the infinitive.
Too much information is inserted between the two parts of the infinitive.
Explanation:
An infinitive is a word/ phrase that functions as an adverb, noun, or adjective. Infinitives are identified by the use of "to+verb" in the sentence.
Splitting an infinitive is when the "to+verb" structure is disrupted by the addition of an adverb between the two parts of the infinitive. That means an adverb is inserted in-between "to" and "Verb", thus making it "to+adverb+verb" form.
Therefore, writers should avoid splitting infinitives when <u>the sentence is already clear</u>, for the adverb in the infinitive becomes redundant. Moreover, splitting an infinitive must also be avoided if <u>its use makes the sentence awkward</u> and <u>too much information has already been inserted in between the two parts of the infinitive</u>.
