Given the task definition, example input & output, solve the new input case.
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) the answer is unique, (iv) its answer is a continous 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 
Example: "story": "Traditionally considered the last part of the Stone Age, the Neolithic followed the terminal Holocene Epipaleolithic period and commenced with the beginning of farming, which produced the "Neolithic Revolution". It ended when metal tools became widespread (in the Copper Age or Bronze Age; or, in some geographical regions, in the Iron Age). The Neolithic is a progression of behavioral and cultural characteristics and changes, including the use of wild and domestic crops and of domesticated animals. 

The beginning of the Neolithic culture is considered to be in the Levant (Jericho, modern-day West Bank) about 10,200 – 8,800 BC. It developed directly from the Epipaleolithic Natufian culture in the region, whose people pioneered the use of wild cereals, which then evolved into true farming. The Natufian period was between 12,000 and 10,200 BC, and the so-called "proto-Neolithic" is now included in the Pre-Pottery Neolithic (PPNA) between 10,200 and 8,800 BC. As the Natufians had become dependent on wild cereals in their diet, and a sedentary way of life had begun among them, the climatic changes associated with the Younger Dryas are thought to have forced people to develop farming."
Output: What did Neolithic follow?
This question is based on the following sentence in the passage - the Neolithic followed the terminal Holocene Epipaleolithic period and this is answerable from the passage. So, it is a good question.

New input case for you: My name is Sandra. Let me tell you the story of the best meal I ever had. 

I was sitting on the school bench outside Springfield Elementary School, waiting to pick up my granddaughter. She is a real cutie, and I am very proud of her grades. To pass the time, I played my triangle. In my youth, I was a triangle player in a large New York band, the Black Triangles. We all wore full black costumes every time we played. 

"What lovely triangle music! You make me think of a friend I had once upon a time." 

A strange lady, about my age, was standing next to me, talking! She was holding a trumpet. It turns out the strange lady was my old friend and Black Triangle trumpet player Matilda. We hadn't seen each other since New York. Matilda told me she wanted to keep in touch, but couldn't remember what I looked like! We found out that all we remembered were the black costumes we always wore! It turns out; Matilda was also there to pick someone up from school. 

"Well, Sandra, why don't you join me and my grandson for lunch? There is a lovely Thai place right down the road.' 

We went there with my granddaughter and her grandson, and had a delicious meal. Our grandchildren got married 15 years later.
