Input: Read this: Some bar-tailed godwits Limosa lapponica have the longest known non-stop flight of any migrant, flying 11,000 km from Alaska to their New Zealand non-breeding areas. Prior to migration, 55 percent of their bodyweight is stored as fat to fuel this uninterrupted journey.
Question: How much of the bar-tailed godwits bodyweight is stored as fat before migration?

Output: 55 percent


Input: Read this: As of 2010, the maternal mortality rate was 560 deaths/100,000 live births, and the infant mortality rate was 59.34 deaths/1,000 live births. Female genital mutilation (FGM) is rare in the country, being confined to limited geographic areas of the country.
Question: What is the infant mortality rate in South Africa?

Output: unanswerable


Input: Read this: Another effective way to decrease the transmission rate of infectious diseases is to recognize the effects of small-world networks. In epidemics, there are often extensive interactions within hubs or groups of infected individuals and other interactions within discrete hubs of susceptible individuals. Despite the low interaction between discrete hubs, the disease can jump to and spread in a susceptible hub via a single or few interactions with an infected hub. Thus, infection rates in small-world networks can be reduced somewhat if interactions between individuals within infected hubs are eliminated (Figure 1). However, infection rates can be drastically reduced if the main focus is on the prevention of transmission jumps between hubs. The use of needle exchange programs in areas with a high density of drug users with HIV is an example of the successful implementation of this treatment method.  Another example is the use of ring culling or vaccination of potentially susceptible livestock in adjacent farms to prevent the spread of the foot-and-mouth virus in 2001.
Question: When was vaccination used to prevent the spread of the foot-and-mouth virus?

Output: 2001


Input: Read this: On June 28, 1776, General Sir Henry Clinton along with 2,000 men and a naval squadron tried to seize Charles Towne, hoping for a simultaneous Loyalist uprising in South Carolina. When the fleet fired cannonballs, they failed to penetrate Fort Sullivan's unfinished, yet thick, palmetto-log walls. No local Loyalists attacked the town from the mainland side, as the British had hoped they would do. Col. Moultrie's men returned fire and inflicted heavy damage on several of the British ships. The British were forced to withdraw their forces, and the Americans renamed the defensive installation as Fort Moultrie in honor of its commander.
Question: Who was the commander of the American forces defending South Carolina?

Output:
Col. Moultrie
