Question: Read this and answer the question

A permanent European presence in New Netherland began in 1624 – making New York the 12th oldest continuously occupied European-established settlement in the continental United States  – with the founding of a Dutch fur trading settlement on Governors Island. In 1625, construction was started on a citadel and a Fort Amsterdam on Manhattan Island, later called New Amsterdam (Nieuw Amsterdam). The colony of New Amsterdam was centered at the site which would eventually become Lower Manhattan. The Dutch colonial Director-General Peter Minuit purchased the island of Manhattan from the Canarsie, a small band of the Lenape, in 1626 for a value of 60 guilders (about $1000 in 2006); a disproved legend says that Manhattan was purchased for $24 worth of glass beads.

On what island did the Dutch set up a settlement to trade furs?
Answer: Governors Island


Problem: In the revival movement France held a foremost place, owing to the reputation and convincing power of the orator, Jean-Baptiste Henri Lacordaire (1802–1861). He took the habit of a Friar Preacher at Rome (1839), and the province of France was canonically erected in 1850. From this province were detached the province of Lyon, called Occitania (1862), that of Toulouse (1869), and that of Canada (1909). The French restoration likewise furnished many laborers to other provinces, to assist in their organization and progress. From it came the master general who remained longest at the head of the administration during the 19th century, Père Vincent Jandel (1850–1872). Here should be mentioned the province of St. Joseph in the United States. Founded in 1805 by Edward Fenwick, afterwards first Bishop of Cincinnati, Ohio (1821–1832), this province has developed slowly, but now ranks among the most flourishing and active provinces of the order. In 1910 it numbered seventeen convents or secondary houses. In 1905, it established a large house of studies at Washington, D.C., called the Dominican House of Studies. There are now four Dominican provinces in the United States.
What title did Pere Vincent Jandel hold during this time?
The answer is the following: master general


Input: Article: Mastic asphalt is a type of asphalt which differs from dense graded asphalt (asphalt concrete) in that it has a higher asphalt/bitumen (binder) content, usually around 7–10% of the whole aggregate mix, as opposed to rolled asphalt concrete, which has only around 5% added asphalt/bitumen. This thermoplastic substance is widely used in the building industry for waterproofing flat roofs and tanking underground. Mastic asphalt is heated to a temperature of 210 °C (410 °F) and is spread in layers to form an impervious barrier about 20 millimeters (0.79 inches) thick.

Now answer this question: What is the usual thickness of the mastic spread on roofs?

Output:
20 millimeters
