Which is correct?
When using a dynamic link library (DLL), updates are ______ to apply to each module without affecting other parts of the program.
B. more easily
Easier is an adjective and more easily is an adverbial phrase. Easier describes “updates”, not how they are applied.
A good way to remember the difference:
That was the easier answer (adjective).
You answered it more easily than I could have done it (adverbial phrase).
