Grammar Question

<p>Her thesis explained what motivated Stiller and Meara to give up their separate theatrical careers in favor of becoming a comedy duo in the late 1960’s.</p>

<p>Is the phrase “in favor of” used grammatically correct in this sentence? Or should I use the infinitive “to become”? Also, when is the phrase “in which” properly used (with people, places, etc.)? Please help! Thanks.</p>

<p>“In favor of” is correct.</p>

<p>Ex. Hydrolysis is a chemical process in which water molecules are added to break monomers.</p>
