Input: Read this: On February 29, 2012, Microsoft released Windows 8 Consumer Preview, the beta version of Windows 8, build 8250. Alongside other changes, the build removed the Start button from the taskbar for the first time since its debut on Windows 95; according to Windows manager Chaitanya Sareen, the Start button was removed to reflect their view that on Windows 8, the desktop was an "app" itself, and not the primary interface of the operating system. Windows president Steven Sinofsky said more than 100,000 changes had been made since the developer version went public. The day after its release, Windows 8 Consumer Preview had been downloaded over one million times. Like the Developer Preview, the Consumer Preview expired on January 15, 2013.
Question: How many times was the Consumer Preview downloaded in the first 42 hours?

Output: unanswerable

QUES: The clock does not run during convert attempts in the last three minutes of a half. If the 15 minutes of a quarter expire while the ball is live, the quarter is extended until the ball becomes dead. If a quarter's time expires while the ball is dead, the quarter is extended for one more scrimmage. A quarter cannot end while a penalty is pending: after the penalty yardage is applied, the quarter is extended one scrimmage. Note that the non-penalized team has the option to decline any penalty it considers disadvantageous, so a losing team cannot indefinitely prolong a game by repeatedly committing infractions.

If a quarter's time expires while the ball is pending how long is the quarter extended?
What is the answer?

QUES: Pubertal development also affects circulatory and respiratory systems as an adolescents' heart and lungs increase in both size and capacity. These changes lead to increased strength and tolerance for exercise. Sex differences are apparent as males tend to develop "larger hearts and lungs, higher systolic blood pressure, a lower resting heart rate, a greater capacity for carrying oxygen to the blood, a greater power for neutralizing the chemical products of muscular exercise, higher blood hemoglobin and more red blood cells".
Which sex tends to have more red blood cells than the other?

ANS: males

Comprehensive schools have been accused of grade inflation after a study revealed that Gymnasium senior students of average mathematical ability found themselves at the very bottom of their class and had an average grade of "Five", which means "Failed". Gesamtschule senior students of average mathematical ability found themselves in the upper half of their class and had an average grade of "Three Plus". When a central Abitur examination was established in the State of North Rhine-Westphalia, it was revealed that Gesamtschule students did worse than could be predicted by their grades or class rank. Barbara Sommer (Christian Democratic Union), Education Minister of North Rhine-Westphalia, commented that: Looking at the performance gap between comprehensives and the Gymnasium [at the Abitur central examination] [...] it is difficult to understand why the Social Democratic Party of Germany wants to do away with the Gymnasium. [...] The comprehensives do not help students achieve [...] I am sick and tired of the comprehensive schools blaming their problems on the social class origins of their students. What kind of attitude is this to blame their own students? She also called the Abitur awarded by the Gymnasium the true Abitur and the Abitur awarded by the Gesamtschule "Abitur light". As a reaction, Sigrid Beer (Alliance '90/The Greens) stated that comprehensives were structurally discriminated against by the government, which favoured the Gymnasiums. She also said that many of the students awarded the Abitur by the comprehensives came from "underprivileged groups" and sneering at their performance was a "piece of impudence".
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Which German minister criticized comprehensive schools' ability to help students succeed?
Ah, so.. Barbara Sommer

Input: Read this: Calls are used for a variety of purposes, including mate attraction, evaluation of potential mates, bond formation, the claiming and maintenance of territories, the identification of other individuals (such as when parents look for chicks in colonies or when mates reunite at the start of breeding season), and the warning of other birds of potential predators, sometimes with specific information about the nature of the threat. Some birds also use mechanical sounds for auditory communication. The Coenocorypha snipes of New Zealand drive air through their feathers, woodpeckers drum territorially, and palm cockatoos use tools to drum.
Question: Which type of birds use tools to drum?

Output:
palm
