In this task, you're expected to write answers to questions involving multiple references to the same entity. The answer to the question should be unambiguous and a phrase in the paragraph. Most questions can have only one correct answer.

Passage: Paraceratherium is an extinct genus of hornless rhinoceros, and one of the largest terrestrial mammals that has ever existed. It lived from the early to late Oligocene epoch (34–23 million years ago); its remains have been found across Eurasia between China and the Balkans. It is classified as a member of the hyracodont subfamily Indricotheriinae. Paraceratherium means "near the hornless beast", in reference to Aceratherium, the genus in which the type species P. bugtiense was originally placed.
The exact size of Paraceratherium is unknown because of the incompleteness of the fossils. Its weight is estimated to have been 15 to 20 tonnes (33,000 to 44,000 lb) at most; the shoulder height was about 4.8 metres (15.7 feet), and the length about 7.4 metres (24.3 feet). The legs were long and pillar-like. The long neck supported a skull that was about 1.3 metres (4.3 ft) long. It had large, tusk-like incisors and a nasal incision that suggests it had a prehensile upper lip or proboscis (trunk). The lifestyle of Paraceratherium may have been similar to that of modern large mammals such as the elephants and extant rhinoceroses. Because of its size, it would have had few predators and a slow rate of reproduction. It was a browser, eating mainly leaves, soft plants, and shrubs. It lived in habitats ranging from arid deserts with a few scattered trees to subtropical forests. The reasons for the animal's extinction are unknown, but various factors have been proposed. 
Question: What quality of Paraceratherium's probably meant it didn't have many animals trying to eat it?

Ex Output:
its size.

Passage: Half of Minneapolis–Saint Paul residents work in the city where they live. Most residents drive cars, but 60% of the 160,000 people working downtown commute by means other than a single person per auto. The Metropolitan Council's Metro Transit, which operates the light rail system and most of the city's buses, provides free travel vouchers through the Guaranteed Ride Home program to allay fears that commuters might otherwise be occasionally stranded if, for example, they work late hours.On January 1, 2011, the city's limit of 343 taxis was lifted.Minneapolis currently has two light rail lines and one commuter rail line. The METRO Blue Line LRT (formerly the Hiawatha Line) serves 34,000 riders daily and connects the Minneapolis–Saint Paul International Airport and Mall of America in Bloomington to downtown. Most of the line runs at surface level, although parts of the line run on elevated tracks (including the Franklin Avenue and Lake Street/Midtown stations) and approximately 2 miles (3.2 km) of the line runs underground, including the Lindbergh terminal subway station at the airport. 
Question: What is the former name of the line that has a terminal subway station at the airport?

Ex Output:
Hiawatha Line.

Passage: Along with the rest of Trafford, Stretford maintains a selective education system assessed by the 11-plus examination.
The proportion of pupils leaving Stretford Grammar School with five or more GCSEs at grades A*–C in 2006, was 98.3%, compared to an average of 66.7% for all secondary schools in Trafford and a national UK average of 61.3%. The proportion of students from minority ethnic backgrounds, and for whom English is an additional language, is much higher than the average. Stretford Grammar was awarded specialist Science College status in September 2005. The school was assessed as "good" in its April 2015 Ofsted report.Stretford High School Community Languages College, like Stretford Grammar, has a much higher proportion than the national average of pupils with a first language other than English, many of them being either asylum seekers or refugees. In 2004 Stretford High School was made subject to special measures, as it was considered not to be providing an adequate education for its pupils. Substantial improvement has taken place since then; the school was assessed as "satisfactory" in its November 2005 Ofsted report and was removed from special measures. Further improvements saw Stretford High School gain an "outstanding" assessment from Ofsted, following its February 2008 inspection. GCSE results also placed the school in the top 1% of schools in the country for adding value to its students.Stretford also has the specialist Arts College, Lostock College.
Plans to build a new university in the town, to be known as University Academy 92, were announced in September 2017. A branch of Lancaster University, it hopes to welcome the first of its anticipated 6500 students in September 2019. The campus is to be built on the Kelloggs headquarters site on Talbot Road, which has already been acquired by Trafford Council for £12 million. 
Question: What is the name of the school that was rated in the top 1% of schools in the country for adding value to its students?

Ex Output:

Stretford High School.
