Thanks for the response, but I asked precisely because 1.) it was not accepted, and 2.) the question was not of the "choose all correct answers" variety, else it would be obvious as to why the answer was not accepted. It was of the "drop-down" variety, where you can select only one response. I was told that "heureuses" was incorrect, that "heureux" was correct, and when I selected "heureux" later in the lesson, when the question was reintroduced, it was marked correct. From what you're saying, it sounds like a "glitch"--I wanted to check before reporting it. Thanks, again.
Can anyone provide clarification on this liaison? In the audio the liaison seems to create an additional syllable, and I'm hoping for clarification as to whether that's an error or something new I need to learn. I would have thought this would be pronounced something like "nous somm- zeureux" but instead it is "nous somm- uh-zeureux." Many thanks.
