Answer:
31. Chat
32. driving
33. comes
34. put
35. seen
36. was built (17th century implies it was built previously, not is being built or will be built)
37. Will join (I'm going is the verb in the previous sentence, and it is future tense)
Step-by-step explanation:
Match the verb tenses. EX: for 32, "used" is past tense, so drive should be as well. This makes driving.
