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.

[Q]: Passage: In 1700 several hundred French Huguenots migrated from England to the colony of Virginia, where the English Crown had promised them land grants in Lower Norfolk County. When they arrived, colonial authorities offered them instead land 20 miles above the falls of the James River, at the abandoned Monacan village known as Manakin Town, now in Powhatan County. Some settlers landed in present-day Chesterfield County. On 12 May 1705, the Virginia General Assembly passed an act to naturalise the 148 Huguenots still resident at Manakintown. Of the original 390 settlers in the isolated settlement, many had died; others lived outside town on farms in the English style; and others moved to different areas. Gradually they intermarried with their English neighbors. Through the 18th and 19th centuries, descendants of the French migrated west into the Piedmont, and across the Appalachian Mountains into the West of what became Kentucky, Tennessee, Missouri, and other states. In the Manakintown area, the Huguenot Memorial Bridge across the James River and Huguenot Road were named in their honor, as were many local features, including several schools, including Huguenot High School.
[A]: How many French Huguenots eventually moved to Missouri from Manakin Town?

[Q]: Passage: Harvard's academic programs operate on a semester calendar beginning in early September and ending in mid-May. Undergraduates typically take four half-courses per term and must maintain a four-course rate average to be considered full-time. In many concentrations, students can elect to pursue a basic program or an honors-eligible program requiring a senior thesis and/or advanced course work. Students graduating in the top 45% of the class are awarded degrees summa cum laude, students in the next 15% of the class are awarded magna cum laude, and the next 30% of the class are awarded cum laude. Harvard has chapters of academic honor societies such as Phi Beta Kappa and various committees and departments also award several hundred named prizes annually. Harvard, along with other universities, has been accused of grade inflation, although there is evidence that the quality of the student body and its motivation have also increased. Harvard College reduced the number of students who receive Latin honors from 90% in 2004 to 60% in 2005. Moreover, the honors of "John Harvard Scholar" and "Harvard College Scholar" will now be given only to the top 5 percent and the next 5 percent of each class.
[A]: What does a basic program also require?

[Q]: Passage: Neptune's weather is characterised by extremely dynamic storm systems, with winds reaching speeds of almost 600 m/s (2,200 km/h; 1,300 mph)nearly reaching supersonic flow. More typically, by tracking the motion of persistent clouds, wind speeds have been shown to vary from 20 m/s in the easterly direction to 325 m/s westward. At the cloud tops, the prevailing winds range in speed from 400 m/s along the equator to 250 m/s at the poles. Most of the winds on Neptune move in a direction opposite the planet's rotation. The general pattern of winds showed prograde rotation at high latitudes vs. retrograde rotation at lower latitudes. The difference in flow direction is thought to be a "skin effect" and not due to any deeper atmospheric processes. At 70 S latitude, a high-speed jet travels at a speed of 300 m/s.
[A]:
What calm weather does Neptune have?
