Listen to the audio and answer the question below.
How can you respond to Bob's question using the word since?
I have been focusing on this evaluation since last week.
I will focus on this evaluation since tomorrow.
The use of since here is not appropriate because it refers to a future action rather than something that has already started.

In the Present Perfect Continuous tense, since is used to indicate the starting point of an action that began in the past and continues into the present, making it clear that Bob is still engaged with the evaluation process.
