Hi, my name is Marie (or kiara) I'm French, I would like to know the difference between who and whom in English.

Merci d'avance.

...

Explanation:

Whom should be used to refer to the object of a verb or preposition. When in doubt, try this simple trick: If you can replace the word with “he”' or “'she,” use who. If you can replace it with “him” or “her,” use whom. Who should be used to refer to the subject of a sentence.

b. they require a huge investment of time, dedication ,training, and patience almost from the day they are born.

explanation:

the sentence gives a clear evidence of how carefully the sar dogs are selected and also specify from what time this exercise begins."almost from the day they are are born." this sentence shows as that this exercise begins early.

if you need any clarification or more explanation pls do mention in the comment section.
