Input: Consider Input: Passage: During the civil war, and the ensuing Soviet–Afghan War, most of the countrys infrastructure was destroyed, and normal patterns of economic activity were disrupted. The gross national product (GNP) fell substantially during Karmals rule because of the conflict; trade and transport were disrupted along with the loss of labor and capital. In 1981 the Afghan GDP stood at 154.3 billion Afghan afghanis, a drop from 159,7 billion in 1978. GNP per capita decreased from 7,370 in 1978 to 6,852 in 1981. The most dominant form of economic activity was the Agriculture in Afghanistan. Agriculture accounted for 63 percent of gross domestic product (GDP) in 1981; 56 percent of the labour force worked in agriculture in 1982. Industry accounted for 21 percent of GDP in 1982, and employed 10 percent of the labour force. All industrial enterprises were government-owned. The service sector, the smallest of the three, accounted for 10 percent of GDP in 1981, and employed an estimated one-third of the labour force.

Input: Consider Input: Passage: Wearing bright orange uniforms and showing their speed on defense and special teams, the Chicago Bears overwhelmed the 49ers who were coming off their Bye Week. They jumped to a 24-0 first-quarter lead and 41-0 halftime cushion before coasting to a 41-10 victory. Brian Urlacher's one-handed interception was headed to the highlight reel as soon as he tumbled to the ground after somehow batting the ball to himself. Urlacher's stellar play symbolized what kind of afternoon it was for the refreshed and still unbeaten Chicago Bears - and how frustrating the day was for the San Francisco 49ers. San Francisco entered giving up 32 points a game, but the defense wasn't to fault early on because turnovers allowed the Bears to work from short fields. Drives started at the 15, 41 and 13, and they turned all three into touchdowns to take the big opening-quarter lead. The 49ers coughed up the ball a fourth time late in the half when WR Antonio Bryant caught a pass and fumbled, with CB Ricky Manning Jr. recovering. San Francisco averted a shutout in the fourth quarter on a 23-yard field goal by K Joe Nedney and a 16-yard TD pass from Smith to WR Antonio Bryant. QB Alex Smith finished 16 of 26 for 146 yards. RB Frank Gore rushed for 111 yards on 12 carries, thanks to a 53-yard run. The 49ers now stand at 2-5. 
Question: How many touchdowns did Bears make in the first half of the game? 
Answer type: Number 

Output: 4.


Input: Consider Input: Passage: Some sources state that three million Circassians were evicted from Circassia in a period lasting until 1911. Other sources cite upwards of two million Circassian refugees fleeing Circassia by 1914 and entering nations and regions such as the Balkans, Turkey, what was the Ottoman Empire in what was known as the Muhajir, Iran, the Qajar dynasty also as Muhajir, Syria, Lebanon, what is now Jordan, Kosovo, Egypt , Israel  and as far afield as upstate New York and New Jersey. Some 90 percent of people with Circassian descent now live in other countries, primarily in Turkey, Jordan and other countries of the Middle East, with only 300,000-400,000 remaining in what is now Russia. The depopulated Circassian lands were resettled by numerous ethnic groups, including Russians, Ukrainians and Georgians. Friction developed between the latter group and the remaining indigenous people in Abkhazia, a factor later contributing to friction between the two ethnic groups and the resulting War in Abkhazia. 
Question: How many ethnic groups resettled the depopulated Circassian lands? 
Answer type: Number 


Output: 3.
