Teacher: You will be given three sentences. Read them, then identify a noun phrase (person, place, or thing) or event that is shared between all three sentences. As the output, write the span of the text corresponding to that phrase in each sentence. Keep the order of the sentences, that is, your answer should look like: 1: *a phras from sentence 1e* 2: *a phras from sentence 2* 3: *a phrase from sentence 3*
Teacher: Now, understand the problem? If you are still confused, see the following example:
sentence 1: Four employees of the store have been arrested , but its manager -- herself a woman -- was still at large Saturday , said Goa police superintendent Kartik Kashyap . sentence 2: If convicted , they could spend up to three years in jail , Kashyap said . sentence 3: The four store workers arrested could spend 3 years each in prison if convicted .
Solution: sentence 1: Four employees of the store sentence 2: they sentence 3: The four store workers
Reason: All three mentioned parts refer to the same entity, the four eployees. "Of the store" in first sentence must be included, since it is part of the same noun phrase describing the employees.
