Question

fill in the blank: il semble quil ____ reconnaître ses erreurs.
sait
peut
sache
a

Explanation:

In French, after "Il semble que", we use the subjunctive mood. The verb "savoir" (to know) in the subjunctive for "il" is "sache". "Sait" is the indicative present, "peut" means "can" (indicative or subjunctive but doesn't fit context here), and "a" is "has" which doesn't fit. So the correct form is "sache".

Answer:

C. sache
