Problem: Military history of the United States:

The Persian Gulf War was a conflict between Iraq and a coalition force of 34 nations led by the United States. The lead up to the war began with the Iraqi invasion of Kuwait in August 1990 which was met with immediate economic sanctions by the United Nations against Iraq. The coalition commenced hostilities in January 1991, resulting in a decisive victory for the U.S. led coalition forces, which drove Iraqi forces out of Kuwait with minimal coalition deaths. Despite the low death toll, over 180,000 US veterans would later be classified as "permanently disabled" according to the US Department of Veterans Affairs (see Gulf War Syndrome). The main battles were aerial and ground combat within Iraq, Kuwait and bordering areas of Saudi Arabia. Land combat did not expand outside of the immediate Iraq/Kuwait/Saudi border region, although the coalition bombed cities and strategic targets across Iraq, and Iraq fired missiles on Israeli and Saudi cities.

When did hostilities in the Persian Gulf War begin?

A: January 1991

Problem: Late Middle Ages:

The marriage of Richard II of England to Anne of Bohemia established contacts between the two nations and brought Lollard ideas to her homeland. The teachings of the Czech priest Jan Hus were based on those of John Wycliffe, yet his followers, the Hussites, were to have a much greater political impact than the Lollards. Hus gained a great following in Bohemia, and in 1414, he was requested to appear at the Council of Constance to defend his cause. When he was burned as a heretic in 1415, it caused a popular uprising in the Czech lands. The subsequent Hussite Wars fell apart due to internal quarrels and did not result in religious or national independence for the Czechs, but both the Catholic Church and the German element within the country were weakened.

What weren't the followers of Jan Hus called?

A: unanswerable

Problem: Pesticide:

The term "push-pull" was established in 1987 as an approach for integrated pest management (IPM). This strategy uses a mixture of behavior-modifying stimuli to manipulate the distribution and abundance of insects. "Push" means the insects are repelled or deterred away from whatever resource that is being protected. "Pull" means that certain stimuli (semiochemical stimuli, pheromones, food additives, visual stimuli, genetically altered plants, etc.) are used to attract pests to trap crops where they will be killed. There are numerous different components involved in order to implement a Push-Pull Strategy in IPM.
