Monday morning and thinking time again. Here's one more appropriate to this forum.
In the following sentences replace "?" with any integer number spelled out and "??" with "first", "second", "third" or last"; so that all the sentences are true.
There are ? Hs in the ?? sentence.
There are ? Fs in the ?? sentence.
There are ? Ts in the ?? sentence.
There are ? Es in all the sentences.
Two solutions are known but there may be more.
