Should I say “them or those”?
When I explained some necessary complex ideas, I explained them/those using examples.
“Them” should be correct, and “those” should be incorrect. However, the grammar checking system of MS word suggests “those” is correct.
The correct word is "them" but the sentence is quite repetitive.
To explain complex ideas, I used examples.
I used examples to [help] explain complex ideas.
When I must explain complex ideas, I find using examples help make them more clear.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
