I just asked it with Gemini; at first, it got it right. Then I asked if it was sure and it apologised and said 3 is the correct answer. When asked what are the 3 "e"s, it says:

> 1. The first "e" is located in the first syllable, between the "g" and the "g".
> 2. The second "e" is located in the second syllable, following the "r".
> 3. The third "e" is located in the third syllable, following the "i" and before the last "o".
