OA:
A
Can someone please explain the difference between help determine VS help to determine?
I have found this:
Help to do something would be someone giving you all the tools to complete a task but not working with you to complete it; while help doing something is a person working with you to complete a task
In C and D,
helps (singular) does not agree with
differences (plural). Eliminate C and D.
In E,
between must refer to two things; it cannot refer only to
how a sound.
Between how a sound is heard AND what? Eliminate E.
In B,
differences in the TWO EARS does not convey the intended meaning. The differences here are not in the ears themselves but in how the two ears HEAR. Eliminate B.
The correct answer is
A.
Certain verbs (
see, hear, watch, make, help) can be combined with the
bare infinitive, the infinitive form of a verb with the
to omitted.
The typical construction is SPECIAL VERB + DIRECT OBJECT + BARE INFINITIVE:
John heard the dog bark. (
bark = bare infinitive,
to bark with the
to omitted)
Susan is watching her son play baseball. (
play = bare infinitive,
to play with the
to omitted)
You made me love you. (love = bare infinitive,
to love with the
to omitted)
In the OA above:
Subtle differences help the listener determine. (
determine = bare infinitive,
to determine with the
to omitted)
