This task is about creating an unanswerable question based on a given passage. Construct a question that looks relevant to the given context but is unanswerable. Following are a few suggestions about how to create unanswerable questions:
(i) create questions which require satisfying a constraint that is not mentioned in the passage
(ii) create questions which require information beyond what is provided in the passage in order to answer
(iii) replace an existing entity, number, date mentioned in the passage with other entity, number, date and use it in the question
(iv) create a question which is answerable from the passage and then replace one or two words by their antonyms or insert/remove negation words to make it unanswerable.

Passage: In this equation, a dimensional constant  is used to describe the relative strength of gravity. This constant has come to be known as Newton's Universal Gravitation Constant, though its value was unknown in Newton's lifetime. Not until 1798 was Henry Cavendish able to make the first measurement of  using a torsion balance; this was widely reported in the press as a measurement of the mass of the Earth since knowing  could allow one to solve for the Earth's mass given the above equation. Newton, however, realized that since all celestial bodies followed the same laws of motion, his law of gravity had to be universal. Succinctly stated, Newton's Law of Gravitation states that the force on a spherical object of mass  due to the gravitational pull of mass  is

Passage: In 1994, responding to the need for a more useful system for describing chronic pain, the International Association for the Study of Pain (IASP) classified pain according to specific characteristics: (1) region of the body involved (e.g. abdomen, lower limbs), (2) system whose dysfunction may be causing the pain (e.g., nervous, gastrointestinal), (3) duration and pattern of occurrence, (4) intensity and time since onset, and (5) etiology. However, this system has been criticized by Clifford J. Woolf and others as inadequate for guiding research and treatment. Woolf suggests three classes of pain : (1) nociceptive pain, (2) inflammatory pain which is associated with tissue damage and the infiltration of immune cells, and (3) pathological pain which is a disease state caused by damage to the nervous system or by its abnormal function (e.g. fibromyalgia, irritable bowel syndrome, tension type headache, etc.).

Passage: Others have rejected that the doctrine of Immaculate Conception exists in Islam, the Quranic account does not confirm the Immaculate Conception exclusively for Mary as in Islam every human child is born pure and immaculate, her sinless birth is thus independent of the Christian docrtrine of original sin as no such doctrine exists in Islam. Moreover, Hannah's prayer in the Quran for her child to remain protected from Satan (Shayṭān) was said after it had already been born, not before and expresses a natural concern any righteous parent would have. The Muslim tradition or hadith, which states that the only children born without the "touch of Satan," were Mary and Jesus. should therefore not be taken in isolation from the Quran, and is to be interpreted within the specific context of exonerating Mary and her child from the charges that were made against them and is not a general statement. The specific mention of Mary and Jesus in this hadith may also be taken to represent a class of people, in keeping with the Arabic language and the Quranic verse [O Satan] surely thou shalt have no power over My servants, except such of the erring ones as choose to follow thee (15:42)
