Question

Correct the underlined part of the sentence. If there is no error choose "no change."

In everything from finding comets to spotting supernovae, amateur astronomers have become so accomplished, and professional astronomers sometimes seek their help.

• A. No change
• B. Accomplished, also
• C. Accomplished that
• D. Accomplished therefore
• E. Accomplished when

Answer 1

The correct option is C Accomplished that

The use of the idiom 'so' must be followed by 'that' to complete the idiomatic phrase. Only option C does this. So, C is the answer.
