Here is a question about this article: Melatonin is absent from the system or undetectably low during daytime. Its onset in dim light, dim-light melatonin onset (DLMO), at roughly 21:00 (9 p.m.) can be measured in the blood or the saliva. Its major metabolite can also be measured in morning urine. Both DLMO and the midpoint (in time) of the presence of the hormone in the blood or saliva have been used as circadian markers. However, newer research indicates that the melatonin offset may be the more reliable marker. Benloucif et al. found that melatonin phase markers were more stable and more highly correlated with the timing of sleep than the core temperature minimum. They found that both sleep offset and melatonin offset are more strongly correlated with phase markers than the onset of sleep. In addition, the declining phase of the melatonin levels is more reliable and stable than the termination of melatonin synthesis.
What is the answer to this question: What chemical is absent or low during daylight?
****
So... Melatonin

Problem: Please answer a question about the following article about University:
In Canada, "college" generally refers to a two-year, non-degree-granting institution, while "university" connotes a four-year, degree-granting institution. Universities may be sub-classified (as in the Macleans rankings) into large research universities with many PhD granting programs and medical schools (for example, McGill University); "comprehensive" universities that have some PhDs but aren't geared toward research (such as Waterloo); and smaller, primarily undergraduate universities (such as St. Francis Xavier).
How many years does a degree-granting university in Canada spend teaching students?
A: four


Question: Read this and answer the question

The region covers an area of 1,579 square kilometres (610 sq mi). The population density is 5,177 inhabitants per square kilometre (13,410/sq mi), more than ten times that of any other British region.

Sandringham House and Balmoral Castle are privately owned by the Queen. The British Crown Estate – with holdings of £9.4 billion in 2014 – is held in trust by the sovereign and cannot be sold or owned by Elizabeth in a private capacity.
What Scottish estate is privately owned by Elizabeth?
The answer is the following: Balmoral Castle


Input: Article: In the early 20th century came another turn toward nationalist politics with Solidaridad Gallega (1907–1912) modeled on Solidaritat Catalana in Catalonia.
