Hi,

could you please help me to sort this out:

answer c)"happend" without -ed
answer c)in test "happened" with -ed :

is it normal for english grammar or
maybe it is done by pupose to confuse poor students
Jan

[Torsten]

Hi Jan, happen is the infinitive form and happened can be the simple past form of the past participle.
The tests and the forum help you improve your English.

TOEIC listening, question-response: When were the managers supposed to meet?

[Conchita]

There is a typo in that particular test question:

'happened' is spelt 'happend'.

And that is obviously what has confused Jan.
