A) had been trained over the past two years, and they
B) were trained over the past two years, and they had
C) were trained over the past two years and they have
D) had been trained over the past two years and that they had
E) had been trained over the past two years and that they have
I want to understand more on the 'THAT and THAT' construction. Is this construction only required for 'AND' or this is required for other FANBOYS also.
For example:
Most Americans surveyed think that international environmental treaties are useless now but that they will, or could, be useful in the future.
(A) that they will, or could,
(B) that they would, or could
(C) they will be or could,
(D) think that they will be or could
(E) think the treaties will be or could
Is the construction 'THAT...BUT THAT' is applicable here?
