Question

question 8 of 10
fill in the blanks.
— ce sont ses crèches?
— oui, ce sont __ crèches __ professeur de mathématiques, m. dupont.

a. les/de la
b. les/des
c. les/du
d. la/du

Explanation:

1. For the first blank: The question refers to specific "cahiers" (notebooks) that were already mentioned, so we use the definite article "les" (plural form matching "cahiers"). "Leur" is a possessive adjective/pronoun, which does not fit here as we are not indicating possession again.
2. For the second blank: "professeur de mathématiques, M. Dupont" is a specific, singular masculine noun phrase. The contraction "du" (from "de + le") is used to mean "of the" or to link the noun to its specific owner, which is correct here. "de la" is for feminine singular, "des" is for plural, so they do not fit.

Answer:

C. les/du
