Problem: Given the question: Extract the answer to the question from the following context. Question: Who has begun to help Tajikistan in the war on drug trafficking? Context: Drug trafficking is the major illegal source of income in Tajikistan as it is an important transit country for Afghan narcotics bound for Russian and, to a lesser extent, Western European markets; some opium poppy is also raised locally for the domestic market. However, with the increasing assistance from international organizations, such as UNODC, and cooperation with the US, Russian, EU and Afghan authorities a level of progress on the fight against illegal drug-trafficking is being achieved. Tajikistan holds third place in the world for heroin and raw opium confiscations (1216.3 kg of heroin and 267.8 kg of raw opium in the first half of 2006). Drug money corrupts the country's government; according to some experts the well-known personalities that fought on both sides of the civil war and have held the positions in the government after the armistice was signed are now involved in the drug trade. UNODC is working with Tajikistan to strengthen border crossings, provide training, and set up joint interdiction teams. It also helped to establish Tajikistani Drug Control Agency.

Problem: Given the question: Extract the answer to the question from the following context. Question: What film beside Ektachrome and Fujichorme is designed for pushing? Context: Some high-speed black-and-white films, such as Ilford Delta 3200 and Kodak T-MAX P3200, are marketed with film speeds in excess of their true ISO speed as determined using the ISO testing method. For example, the Ilford product is actually an ISO 1000 film, according to its data sheet. The manufacturers do not indicate that the 3200 number is an ISO rating on their packaging. Kodak and Fuji also marketed E6 films designed for pushing (hence the "P" prefix), such as Ektachrome P800/1600 and Fujichrome P1600, both with a base speed of ISO 400.
