In this task, you're given a passage, further information available on a particular linked term from the statement, and an answer term. Your job is to generate a question that can use the information provided to obtain the given answer. You should use the information on both passage and link information to create the question. Note that the answer to the question should be exactly the given answer, and if the answer is none, the answer to the question shouldn't be obtainable from the passage or linked information.

Ex Input:
Passage: "(When You Gonna) Give It Up to Me" (known as "Give It Up to Me" in its solo version) is a reggaedancehall song written by Sean Paul for his third album The Trinity (2005). The single meant to be released after "Temperature" was "Breakout", but was switched to "Give It Up To Me" to promote the film Step Up (2006). It is the fourth U.S. single taken from the album and the fifth UK single. It was a split single with "Never Gonna Be the Same", which was released outside the North America in June 2006 but it was finally released worldwide in October 2006. The version released as a single (the one called "(When You Gonna) Give It Up to Me", in order to differ from the album version) was a collaboration with Keyshia Cole and the song was a single from the Step Up film soundtrack. Despite The Trinity being re-released just before the single release, the version with Keyshia Cole did not make the album, despite a "radio version" being added.
Link Information: none Answer: none

Ex Output:
How many sales did Sean Paul's third album make?

Ex Input:
Passage: Although originally proposed to the French space agency CNES, it was considered too complex and expensive for a single national programme. Its acceptance within the European Space Agency's scientific programme, in 1980, was the result of a lengthy process of study and lobbying. The underlying scientific motivation was to determine the physical properties of the stars through the measurement of their distances and space motions, and thus to place theoretical studies of stellar structure and evolution, and studies of galactic structure and kinematics, on a more secure empirical basis. Observationally, the objective was to provide the positions, parallaxes, and annual proper motions for some 100,000 stars with an unprecedented accuracy of 0.002arcseconds, a target in practice eventually surpassed by a factor of two. The name of the space telescope, "Hipparcos" was an acronym for High Precision Parallax Collecting Satellite, and it also reflected the name of the ancient Greek astronomer Hipparchus, who is considered the founder of trigonometry and the discoverer of the precession of the equinoxes (due to the Earth wobbling on its axis).
Link Information: when ESRO was merged with ELDO. ESA had ten founding member states: Belgium, Denmark, France, West Germany, Italy, the Netherlands, Spain, Sweden, Switzerland, and the United Kingdom. Answer: Belgium

Ex Output:
What countries make up the agency that Hipparcos was accepted to after being considered too complex for CNES?

Ex Input:
Passage: Natural strontium is a mixture of four stable isotopes: Sr, Sr, Sr, and Sr. Their abundance increases with increasing mass number and the heaviest, Sr, makes up about 82.6% of all natural strontium, though the abundance varies due to the production of radiogenic Sr as the daughter of long-lived beta-decaying Rb. Of the unstable isotopes, the primary decay mode of the isotopes lighter than Sr is electron capture or positron emission to isotopes of rubidium, and that of the isotopes heavier than Sr is electron emission to isotopes of yttrium. Of special note are Sr and Sr. The former has a half-life of 50.6days and is used to treat bone cancer due to strontium's chemical similarity and hence ability to replace calcium. While Sr (half-life 28.90years) has been used similarly, it is also an isotope of concern in fallout from nuclear weapons and nuclear accidents due to its production as a fission product. Its presence in bones can cause bone cancer, cancer of nearby tissues, and leukemia. The 1986 Chernobyl nuclear accident contaminated about 30,000km with greater than 10 kBq/m with Sr, which accounts for 5% of the core inventory of Sr.
Link Information: In the accident's aftermath, 237 people suffered from acute radiation sickness, of whom 31 died within the first three months. Answer: it is roughly estimated that cancer deaths caused by Chernobyl may reach a total of about 4,000

Ex Output:
How many people died in the incident that contaminated about 30,000 km?
