Hi

Look at the test question again:

[Seanmen]

Hi,

what is a "ranking official"?

Hi Torsten

Questions 6 and 7 need repair in this test.

In sentence 6, the word 'has' should be removed from the test question.
In sentence 7, the word 'is' should be removed from the test question.
(The words 'has' and 'is' could either remain in the solutions or the solutions should both be who's.)

Alternatively, option (a) for both questions could be changed to "Who".
.

[Torsten]

Hi Amy,

Thanks a lot for your suggestions, I've removed "has" and "is".
Regards,
Torsten

Oh, dear! Torsten, I think I may have now caused you some needless work.

Did both questions already have 'who' as one of the solution options?
Sorry, if 'who' was already an option, then there was no problem in those sentences and obviously I haven't yet had enough coffee this morning.
.

[Torsten]

Well Amy, either way both sentences are OK now...

It`s a problem with a question #7. "C" answer is incorrect. Why?

[Torsten]

C is correct and there is no problem.

No, Torsten. The system shown 10 of 10 when i had chosen an "a" answer. Due to this fact, the '"a" answer is seemed to be correct.

[Kitosdad]

is deemed to be correct.
