The Small School

At a small school, there are just three teachers: Ms. Shickle, Ms. Muller, and Ms. Pleacher.

Each teacher is knowledgeable in the subjects she teaches.

There are five subjects taught: English, mathematics, history, geography, and French.

You are told the following:

Each teacher teaches three subjects.

Ms. Pleacher does not know what an obtuse angle is.

Ms. Muller is the only teacher who knows where the Gobi desert is located.

Ms. Shickle is no good at foreign languages.

No subject is taught by all three teachers.
