mSKRWe aren't comparing "does" to "summarize." "Does" wouldn't mean anything by itself in this context. Rather, the sentence is saying that Degler does
not merely summarize. He does more things than that. This is a fairly normal construction. We can say that a person/entity does more than one thing by following "more than" with a verb, in which case we want the bare infinitive: the "to" form without the "to".
Today's watches do more than just tell time.
I want a teacher who does more than just tell me the right answers.We can also use a specific verb in place of "does," and then follow up with the objects of the verb. In that case, we are saying that this verb is done to more than one thing. Notice that in both this and the above case, it's common to say "more than just" or "more than merely" to emphasize that we are seeing more than the minimal thing one might expect:
My parrot says more than "Hello" and "Pretty bird."
Our restaurant offers more than just soup and salad Hi
DmitryFarberThanks for answering
I am pretty clear so far and realized my mistake. But another doubt up with A.
I understood this sentence as He does more things/work than merely summarize.
Summarize > things/work
As work/things are ellipsis , on what basis can i reject summarizing.
As some part is elliptical then grammatically
He does working more than just summarizing .
So the reason to reject A:
infinite is better than gerund for general terms. ( He does like to work more than to summarize BETTER THAN He does like working more than summarizing . Choose infinite if no marker is mentioned )
Thanks
