Input: Read this: A UCLA research study published in the June 2006 issue of the American Journal of Geriatric Psychiatry found that people can improve cognitive function and brain efficiency through simple lifestyle changes such as incorporating memory exercises, healthy eating, physical fitness and stress reduction into their daily lives. This study examined 17 subjects, (average age 53) with normal memory performance. Eight subjects were asked to follow a "brain healthy" diet, relaxation, physical, and mental exercise (brain teasers and verbal memory training techniques). After 14 days, they showed greater word fluency (not memory) compared to their baseline performance. No long term follow up was conducted, it is therefore unclear if this intervention has lasting effects on memory.
Question: How many subjects had the average age of 17?

Output: unanswerable


Input: Read this: In Australia, the formal ceremony of granting assent in parliament has not been regularly used since the early 20th century. Now, the bill is sent to the governor-general's residence by the house in which it originated. The governor-general then signs the bill, sending messages to the President of the Senate and the Speaker of the House of Representatives, who notify their respective houses of the governor-general's action. A similar practice is followed in New Zealand, where the governor-general has not personally granted the Royal Assent in parliament since 1875.
Question: In what year did the New Zealand governor-general last personally grant the royal assent in parliament?

Output: 1875


Input: Read this: The Greek word Χριστιανός (Christianos), meaning "follower of Christ", comes from Χριστός (Christos), meaning "anointed one", with an adjectival ending borrowed from Latin to denote adhering to, or even belonging to, as in slave ownership. In the Greek Septuagint, christos was used to translate the Hebrew מָשִׁיחַ (Mašíaḥ, messiah), meaning "[one who is] anointed." In other European languages, equivalent words to Christian are likewise derived from the Greek, such as Chrétien in French and Cristiano in Spanish.
Question: In which religion does christos mean "one who is anointed'?

Output: unanswerable


Input: Read this: Since chlorinated hydrocarbon pesticides dissolve in fats and are not excreted, organisms tend to retain them almost indefinitely. Biological magnification is the process whereby these chlorinated hydrocarbons (pesticides) are more concentrated at each level of the food chain. Among marine animals, pesticide concentrations are higher in carnivorous fishes, and even more so in the fish-eating birds and mammals at the top of the ecological pyramid. Global distillation is the process whereby pesticides are transported from warmer to colder regions of the Earth, in particular the Poles and mountain tops. Pesticides that evaporate into the atmosphere at relatively high temperature can be carried considerable distances (thousands of kilometers) by the wind to an area of lower temperature, where they condense and are carried back to the ground in rain or snow.
Question: Why are hydrocarbon pesticides not excreted?

Output:
dissolve in fats
