What can be inferred about the speaker's emotional state related to teaching?

Choosing the option that the speaker feels overwhelmed by stress suggests a recognition of a potentially negative emotional state regarding their teaching experience. This interpretation highlights the challenges and pressures often faced by educators, such as managing workloads, student expectations, and the intricate dynamics of a classroom environment.

By selecting this answer, it can be inferred that the speaker's teaching role may be accompanied by feelings of anxiety or burden, indicating that they struggle to cope with the demands of their profession. In contrast, the other options imply more positive or neutral feelings, such as enjoyment or indifference, which do not align with the understanding of someone who is experiencing significant stress.
