Problem: Canadian Armed Forces:

The 2006 renewal and re-equipment effort has resulted in the acquisition of specific equipment (main battle tanks, artillery, unmanned air vehicles and other systems) to support the mission in Afghanistan. It has also encompassed initiatives to renew certain so-called "core capabilities" (such as the air force's medium range transport aircraft fleet the C-130 Hercules and the army's truck and armoured vehicle fleets). In addition, new systems (such as C-17 Globemaster III strategic transport aircraft and CH-47 Chinook heavy-lift helicopters) have also been acquired for the Armed Forces. Although the viability of the Canada First Defence Strategy continues to suffer setbacks from challenging and evolving fiscal and other factors, it originally aimed to:

Problem: Race (human categorization):

In the last two decades of the 18th century, the theory of polygenism, the belief that different races had evolved separately in each continent and shared no common ancestor, was advocated in England by historian Edward Long and anatomist Charles White, in Germany by ethnographers Christoph Meiners and Georg Forster, and in France by Julien-Joseph Virey. In the US, Samuel George Morton, Josiah Nott and Louis Agassiz promoted this theory in the mid-nineteenth century. Polygenism was popular and most widespread in the 19th century, culminating in the founding of the Anthropological Society of London (1863) during the period of the American Civil War, in opposition to the Ethnological Society, which had abolitionist sympathies.

In what century was polygenism most widespread?
---
A: 19th century

Problem: War on Terror:

The origins of al-Qaeda can be traced to the Soviet war in Afghanistan (December 1979 February 1989). The United States, United Kingdom, Saudi Arabia, Pakistan, and the People's Republic of China supported the Islamist Afghan mujahadeen guerillas against the military forces of the Soviet Union and the Democratic Republic of Afghanistan. A small number of "Afghan Arab" volunteers joined the fight against the Soviets, including Osama bin Laden, but there is no evidence they received any external assistance. In May 1996 the group World Islamic Front for Jihad Against Jews and Crusaders (WIFJAJC), sponsored by bin Laden (and later re-formed as al-Qaeda), started forming a large base of operations in Afghanistan, where the Islamist extremist regime of the Taliban had seized power earlier in the year. In February 1998, Osama bin Laden signed a fatwa, as head of al-Qaeda, declaring war on the West and Israel, later in May of that same year al-Qaeda released a video declaring war on the U.S. and the West.

What is the WIJFAJC also known as?

A: unanswerable

Problem: History of India:

The Pala Empire (Bengali: Pal Samrajyo) flourished during the Classical period of India, and may be dated during 7501174 CE. Founded by Gopala I, it was ruled by a Buddhist dynasty from Bengal in the eastern region of the Indian subcontinent. Though the Palas were followers of the Mahayana and Tantric schools of Buddhism, they also patronised Shaivism and Vaishnavism. The morpheme Pala, meaning "protector", was used as an ending for the names of all the Pala monarchs. The empire reached its peak under Dharmapala and Devapala. Dharmapala is believed to have conquered Kanauj and extended his sway up to the farthest limits of India in the northwest. The Pala Empire can be considered as the golden era of Bengal in many ways. Dharmapala founded the Vikramashila and revived Nalanda, considered one of the first great universities in recorded history. Nalanda reached its height under the patronage of the Pala Empire. The Palas also built many viharas. They maintained close cultural and commercial ties with countries of Southeast Asia and Tibet. Sea trade added greatly to the prosperity of the Pala kingdom. The Arab merchant Suleiman notes the enormity of the Pala army in his memoirs.

During what span of time did the Pala Empire thrive?

A:
7501174 CE
