Question: Extract the answer to the question from the following context. Question: A substance that acts as a catalyst to bring about a biochemical reaction is generally called? Context: Antibacterial-resistant strains and species, sometimes referred to as "superbugs", now contribute to the emergence of diseases that were for a while well controlled. For example, emergent bacterial strains causing tuberculosis (TB) that are resistant to previously effective antibacterial treatments pose many therapeutic challenges. Every year, nearly half a million new cases of multidrug-resistant tuberculosis (MDR-TB) are estimated to occur worldwide. For example, NDM-1 is a newly identified enzyme conveying bacterial resistance to a broad range of beta-lactam antibacterials. The United Kingdom's Health Protection Agency has stated that "most isolates with NDM-1 enzyme are resistant to all standard intravenous antibiotics for treatment of severe infections."
Answer: enzyme

Question: Extract the answer to the question from the following context. Question: When could the average person obtain such a vehicle? Context: The Hummers that Schwarzenegger bought 1992 are so large – each weighs 6,300 lb (2,900 kg) and is 7 feet (2.1 m) wide – that they are classified as large trucks, and U.S. fuel economy regulations do not apply to them. During the gubernatorial recall campaign he announced that he would convert one of his Hummers to burn hydrogen. The conversion was reported to have cost about US$21,000. After the election, he signed an executive order to jump-start the building of hydrogen refueling plants called the California Hydrogen Highway Network, and gained a U.S. Department of Energy grant to help pay for its projected US$91,000,000 cost. California took delivery of the first H2H (Hydrogen Hummer) in October 2004.

October 2004
