Could you explain?
Answer
Just as a follow-up to A.Brēza’s reply, I would add:
1) Many people claim to have invented sundaes and many towns around the world pretend to be birthplaces of ice creams.
have invented:
The context is in the past (sundaes already created), but the claim was made and is still ongoing; hence the perfect tense is used.
to be:
The towns are currently pretending (yesterday, today, tomorrow) that they are the birthplace, which is not a one-time action like the creation of sundaes. “Pretend” is followed by to be because it is a catenative verb (?) in this context.
2) It is quite common for a historic high-rise building to be converted into a residential building.
Despite the use of the adjective “historic,” the context of the sentence is not about/in the past; therefore, having been converted would be incorrect because we are not talking about something completed but about a common practice today in the renovation of buildings.
