i got it wrong with the answer "practice"???

[MrPedantic]

Hello Kathryn,

"Practice" is correct; perhaps the test has not yet been amended.

Also, a comma is missing after "me", in the first question:

"......... me what did you do at the weekend?"

Best wishes,

MrP

Dear Sir,
It's hard for me to accept the practice instead of practical.I still don't understand,I'd like more explanation, thank you.

me too wanna know why it is not practical?
always after the "in" , the noun comes?practical is adverb
practical experience and the like right?
in practice is the correct..
but teachers , please make it more clear for me
