A perfect (-ly bad) example of studying vs. expressing
This is classic language busywork. They want you to choose the correct form of the verb. Why even cast doubt about the correct form of the verb? Give me the correct form of the verb, in this case 'Estoy visitando', 'I'm visiting', and then leave the vocabulary blank! Let me say, 'I'm visiting X, I'm visiting Y, Estoy visitando Z'. Verbs are constants, Vocabulary are variables. But here they have the vocabulary fixed (I'll never be asked to express a new thought and tell you somewhere other than pyramids I'm visiting), and all they care about is that I can choose the correct verb, because they think that an activity like this will somehow equate to being able to speak freely. It does the exact opposite of what it supposedly hopes to achieve.
