Relative Pronouns

[laepelba]

I'm working on a translation exercise in my workbook that requires me to translate sentences from English to Spanish using the relative pronoun form with "que".

Some examples: "Tengo el libro que quieres." And, "El hombre que vive en esta casa es actor." And so on.

There are three sentences, though, that don't seem to fit the pattern. They are as follows:
5) Él cree que esta salsa está muy picante.
9) Él no sabe que tengo su billetera.
10) ¿Sabes que la mantequilla es pura grasa?

Are these truly considered "relative pronouns" in the same manner as the other sentences I mentioned? Or did the book mess up (again)?

Thanks!!

I think you're right and in these cases "que" is rather working as a conjunction, not as a relative pronoun.

THANKS!! (whew....)
