Input: Article: Microsoft Windows 3.0 was released in May 1990, and according to a common saying at the time "Windows was not as good as Macintosh, but it was good enough for the average user". Though still a graphical wrapper that relied upon MS-DOS, 3.0 was the first iteration of Windows which had a feature set and performance comparable to the much more expensive Macintosh platform. It also did not help matters that during the previous year Jean-Louis Gassée had steadfastly refused to lower the profit margins on Mac computers. Finally, there was a component shortage that rocked the exponentially-expanding PC industry in 1989, forcing Apple USA head Allan Loren to cut prices which dropped Apple's margins.

Now answer this question: Who was Microsoft Windows 3.0 commonly said to be good enough for?

Output: the average user


Article: In the 1970s the US Law Enforcement Assistance Administration (LEAA) found a reduction of 10% to 13% in Washington, D.C.'s violent crime rate during DST. However, the LEAA did not filter out other factors, and it examined only two cities and found crime reductions only in one and only in some crime categories; the DOT decided it was "impossible to conclude with any confidence that comparable benefits would be found nationwide". Outdoor lighting has a marginal and sometimes even contradictory influence on crime and fear of crime.

Question: What did the LEAA say was reduced 10% to 13% in Washington, DC during daylight savings?
Ans: violent crime rate


Here is a question about this article: After the band's six-night stand at New York's Uris Theatre in May 1974, Brian May collapsed and was diagnosed as having hepatitis. While recuperating, May was initially absent when the band started work on their third album, but he returned midway through the recording process. Released in 1974, Sheer Heart Attack reached number two in the United Kingdom, sold well throughout Europe, and went gold in the United States. It gave the band their first real experience of international success, and was a hit on both sides of the Atlantic. The album experimented with a variety of musical genres, including British music hall, heavy metal, ballads, ragtime, and Caribbean. At this point, Queen started to move away from the progressive tendencies of their first two releases into a more radio-friendly, song-orientated style. Sheer Heart Attack introduced new sound and melody patterns that would be refined on their next album, A Night at the Opera.
What is the answer to this question: What Queen album was released after Sheer Heart Attack?
****
So... A Night at the Opera


The problem: Answer a question about this article:
From the late 18th century to the mid-19th century, large areas of India were annexed by the British East India Company of British Empire. Dissatisfaction with Company rule led to the Indian Rebellion of 1857, after which the British provinces of India were directly administered by the British Crown and witnessed a period of both rapid development of infrastructure and economic stagnation. During the first half of the 20th century, a nationwide struggle for independence was launched with the leading party involved being the Indian National Congress which was later joined by other organizations. The subcontinent gained independence from the United Kingdom in 1947, after the British provinces were partitioned into the dominions of India and Pakistan and the princely states all acceded to one of the new states.
The rapid development of what did British rule cause in India?
****
The answer: infrastructure

Question: Read this and answer the question

According to Y chromosome studies by Sanchez et al. (2005), Cruciani et al. (2004, 2007), the Somalis are paternally closely related to other Afro-Asiatic-speaking groups in Northeast Africa. Besides comprising the majority of the Y-DNA in Somalis, the E1b1b1a (formerly E3b1a) haplogroup also makes up a significant proportion of the paternal DNA of Ethiopians, Sudanese, Egyptians, Berbers, North African Arabs, as well as many Mediterranean populations. Sanchez et al. (2005) observed the M78 subclade of E1b1b in about 77% of their Somali male samples. According to Cruciani et al. (2007), the presence of this subhaplogroup in the Horn region may represent the traces of an ancient migration from Egypt/Libya. After haplogroup E1b1b, the second most frequently occurring Y-DNA haplogroup among Somalis is the West Asian haplogroup T (M70). It is observed in slightly more than 10% of Somali males. Haplogroup T, like haplogroup E1b1b, is also typically found among populations of Northeast Africa, North Africa, the Near East and the Mediterranean.

What percentage of Somali males had DNA containing the M78 subclade of E1b1b?
Answer:
77%
