Good day
Lacking information about energy use, people tend
overestimate the amount of energy used by equipmt
such as lights, that are visible and must be turned o
and off and underestimate that used by unobtrusive
equipment, such as water heaters.
(A) equipment, such as lights, that are visible and
must be turned on and off and underestimate
(B) equipment, such as lights, that are visible and
must be turned on and off and underestimate
when
(C) equipment, such as lights, that is visible and m
be turned on and off and underestimate it whe
(D) visible equipment, such as lights, that must b
turned on and off and underestimate that
(E) visible equipment, such as lights, that must b
turned on and off and underestimate it when
the OA is D but my question is:
Aequipment, such as lights, that are visible and
must be turned on and off and underestimate that
to correct this answer we need to add a "that" in front of must be+(is instead of are)
Am I' correct??
Many thanks in advance
