>!Beena hadn’t heard of Dia.

Baker and artist have heard of each other bc the baker asked the artist to the movie.

Artist refers to teacher when speaking to baker.

Therefore baker would have heard of both the artist and the teacher.

Therefore Beena can’t be the baker.

The artist knows of the baker and teacher clearly because we know she spoke to the baker and was having dinner with the teacher.

Therefore, Beena can’t be the artist.

Therefore, Beena is the teacher.

Beena, the teacher, doesn’t know of Dia, therefore Dia cannot be the artist that Beena is dining with.

Therefore, Dia is the baker.

And there’s only one spot left so Amala is the artist.!<
