Problem: Please answer a question about the following article about Avicenna:
When Ibn Sina was 22 years old, he lost his father. The Samanid dynasty came to its end in December 1004. Ibn Sina seems to have declined the offers of Mahmud of Ghazni, and proceeded westwards to Urgench in modern Turkmenistan, where the vizier, regarded as a friend of scholars, gave him a small monthly stipend. The pay was small, however, so Ibn Sina wandered from place to place through the districts of Nishapur and Merv to the borders of Khorasan, seeking an opening for his talents. Qabus, the generous ruler of Tabaristan, himself a poet and a scholar, with whom Ibn Sina had expected to find asylum, was on about that date (1012) starved to death by his troops who had revolted. Ibn Sina himself was at this time stricken by a severe illness. Finally, at Gorgan, near the Caspian Sea, Ibn Sina met with a friend, who bought a dwelling near his own house in which Ibn Sina lectured on logic and astronomy. Several of Ibn Sina's treatises were written for this patron; and the commencement of his Canon of Medicine also dates from his stay in Hyrcania.
At what age did Avicenna lose his father?
A: 22

Problem: Please answer a question about the following article about Alaska:
Most food in Alaska is transported into the state from "Outside", and shipping costs make food in the cities relatively expensive. In rural areas, subsistence hunting and gathering is an essential activity because imported food is prohibitively expensive. Though most small towns and villages in Alaska lie along the coastline, the cost of importing food to remote villages can be high, because of the terrain and difficult road conditions, which change dramatically, due to varying climate and precipitation changes. The cost of transport can reach as high as 50¢ per pound ($1.10/kg) or more in some remote areas, during the most difficult times, if these locations can be reached at all during such inclement weather and terrain conditions. The cost of delivering a 1 US gallon (3.8 L) of milk is about $3.50 in many villages where per capita income can be $20,000 or less. Fuel cost per gallon is routinely 20–30¢ higher than the continental United States average, with only Hawaii having higher prices.
How much does it cost to transport a gallon of milk in some rural areas of Alaska?
A:
$3.50
