This task is about reading the given passage and construct a question about the information present in the passage. Construct a question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) its answer is a continuous text span from the paragraph. Avoid creating questions that (i) can be answered correctly without actually understanding the paragraph and (ii) uses same words or phrases given in the passage.

Let me give you an example: Passage: The French and Indian War (1754–1763) was the North American theater of the worldwide Seven Years' War. The war was fought between the colonies of British America and New France, with both sides supported by military units from their parent countries of Great Britain and France, as well as Native American allies. At the start of the war, the French North American colonies had a population of roughly 60,000 European settlers, compared with 2 million in the British North American colonies. The outnumbered French particularly depended on the Indians. Long in conflict, the metropole nations declared war on each other in 1756, escalating the war from a regional affair into an intercontinental conflict.
The answer to this example can be: When was the French and Indian War?
Here is why: This question is based on the following sentence in the passage- The French and Indian War (1754–1763) was the North American theater of the worldwide Seven Years' War. It is a common convention to write (start year-end year) beside a historical event to understand when the event happened. You can ask questions like this one about dates, years, other numerals, persons, locations, noun phrases, verb phrases, adjectives, clauses etc. which exist in the paragraph.

OK. solve this:
After the Council, Paul VI contributed in two ways to the continued growth of ecumenical dialogue. The separated brothers and sisters, as he called them, were not able to contribute to the Council as invited observers. After the Council, many of them took initiative to seek out their Catholic counterparts and the Pope in Rome, who welcomed such visits. But the Catholic Church itself recognized from the many previous ecumenical encounters, that much needed to be done within, to be an open partner for ecumenism. To those who are entrusted the highest and deepest truth and therefore, so Paul VI, believed that he had the most difficult part to communicate. Ecumenical dialogue, in the view of Paul VI, requires from a Catholic the whole person: one's entire reason, will, and heart. Paul VI, like Pius XII before him, was reluctant to give in on a lowest possible point. And yet, Paul felt compelled to admit his ardent Gospel-based desire to be everything to everybody and to help all people Being the successor of Peter, he felt the words of Christ, "Do you love me more" like a sharp knife penetrating to the marrow of his soul. These words meant to Paul VI love without limits, and they underscore the Church's fundamental approach to ecumenism.
Answer:
In what city did the pope encourage visits from Catholics from other countries?
