Hmm. Maybe that’s why it took me two times reading through it for me to understand what was going on. Perhaps something got lost in the formatting.
They start of with
“(1) Louis Charles Joseph Blériot (1872–1936) ....he became world famous ....
There are no pronouns in this sentence.”
Huh? The personal pronoun “he” is there.
And then reading further I figured out what they were doing. Sort of.
“This sentence contains the relative pronoun that; it connects commented to the statement made by Le Matin.”
Huh?
Or I’m just stupid. (I never was good at all of the technical grammar stuff.)
He appears is in the second sentence, not the first.
There are no pronouns in the first sentence. The word he you mention is in the second sentence.
They do not teach a lot of grammar in US public schools, and few private ones, so most Americans know only a little bit unless they studied a foreign language, and sometimes not then either.
I didn’t see the other replied about the 1st and 2nd sentences —I didn’t mean to pile on :(
