Please accept heureux/use and content/e for happy. For the bread question, you should accept donner for the verb, and the vous conjugation, because you didn't specify 2nd person informal/singular. The prompt for that question also has an unnecessary "on." Additionally, Please specify that "it's hot" is referring to the weather. As it stands the "it" could be anything, meaning that the verb etre would be logical, as it would be used for literally everything but the weather.
