For this purpose I wanted to avoid Option D.
Hi Avinash, as I mentioned in my post above, option D
cannot be considered
ambiguous, because the
other interpretation (
computers learning their ancient and nearly forgotten language) is non-sensical.
In any case, when two verb forms (
use and
learn in this sentence) are used together in a sentence, then the
first verb determines whether the second verb will be in the
gerund form (
for learning) or in the
infinitive form (
to learn). There are no fixed rules for this, and this is largely an
idiom issue.
Having said that, the good part is that in
most cases, the
infinitive form (
to learn) should be used for the second verb form.
p.s. Our book
EducationAisle Sentence Correction Nirvana discusses
the case of two verb forms appearing together, their application and examples in significant detail. If you or someone is interested, PM me your email-id; I can mail the corresponding section.
