Explanation:
In this dialogue, Kate is talking about her plans for the future, specifically, what she will be doing this time next week. To complete the dialogue, we need to use the correct tense in the gaps.

We use the future continuous tense (will be + verb-ing) to talk about an action that will be in progress at a specific time in the future. In this case, Kate will be lying on a tropical beach this time next week.

Therefore, the correct completion for Kate's sentence is "i'll be lying."

Now let's move on to Leo's response. Leo is contrasting what he will be doing with what Kate will be doing. He mentions that while Kate is relaxing on the beach, he will be stressed out over his project.

To complete Leo's sentence, we need to use the future continuous tense again. So, the correct completion for Leo's sentence is "I'll be stressed out."

Putting it all together, the completed dialogue should read as follows:

Kate: just think, this time next week i'll be lying on a tropical beach.
Leo: while you're relaxing on the beach, I'll be stressed out over my project.
