I tried in Bard just for comparison's sake and it got to 1 while still saying a different number. It's a bit strange, here:

Julia has two sisters!

Here's the reasoning:

1. *Julia's brothers have sisters*: Each of Julia's three brothers has two sisters. This means in total, her brothers have 3 brothers * 2 sisters/brother = 6 sisters.

2. *Those sisters are not additional*: However, it's important to remember that these sisters belong to Julia's brothers, not directly to Julia herself. Julia and her sisters are siblings, not counted among the sisters her brothers have.

3. *Therefore*: Julia has 2 sisters (herself and one other).

So, while Julia's brothers have a total of 6 sisters, only Julia and one other sister are Julia's own sisters.
