Why can't I use "appeared in our home" here?

[TheLearner]

Thanks, Mr. Micawber. But, would it be proper if the phrase "...who we haven't seen in a long time.." will be "...who we haven't seen for a long time.."?

[Mister Micawber]

.
Yes. And the more formal version is 'whom we haven't seen in/for a long time'.

"Grammatically, you can say 'came to our home' but I haven't heard any native speakers ever say it like that."

There a 55 million 'native speakers' in the UK, plus a few million more in Australia, South Africa and possibly Canada, who would find the answer 'to our home' much more natural than 'came by' - unless of course you mean they 'came by car', 'came by taxi' - or 'came [and passed] by'.

I think these two distractors are not sufficiently distinctive: I made the mistake, as you call it, of selecting 'came to our home'.

Hello,

I want to know what this expression means in this context? Thank you for you help.

[Mister Micawber]

Which expression, Mickhael? This is a long thread.

(PS: I didn't write the question, Linda did; that was a just a joke.)

So, what is the difference between come by and come over?
Thanks..

Hi

Sorry but everybody asked many questions about the options but nobody about the correct answer that is "came by", I still don't understand why "came by" came by (to the park, to my mom´s house,...or where) I read this sentences incomplete, but I know with your explanation I will get clearer, thank all of you

[Mister Micawber]

'Come by' is the appropriate idiom for this question. It means 'visit informally'. 'Come over' means the same, but it is not an option in this question.
