Question

over the past four years, umberto has worked to designing the perfect bathing suit that makes everyone look ten pounds thinner.

which choice makes the sentence grammatically acceptable?
f no change
g has been working to design
h having been working to design
j working to design

Explanation:

1. The original phrase "has worked to designing" is grammatically incorrect. The structure "work to" requires a base verb form (infinitive), not a gerund (-ing form).
2. Option F is invalid for the above reason.
3. Option H ("having been working to design") creates a sentence fragment, as it lacks a main conjugated verb.
4. Option J ("working to design") also creates a sentence fragment, as it uses a participle instead of a conjugated verb for the main clause.
5. Option G ("has been working to design") uses the correct present perfect continuous tense (appropriate for an action spanning "the past four years") and the correct infinitive form "to design" after "working".

Answer:

G. has been working to design
