Problem: Please answer a question about the following article about Time:
Psychoactive drugs can impair the judgment of time. Stimulants can lead both humans and rats to overestimate time intervals, while depressants can have the opposite effect. The level of activity in the brain of neurotransmitters such as dopamine and norepinephrine may be the reason for this. Such chemicals will either excite or inhibit the firing of neurons in the brain, with a greater firing rate allowing the brain to register the occurrence of more events within a given interval (speed up time) and a decreased firing rate reducing the brain's capacity to distinguish events occurring within a given interval (slow down time).
The level of what is the reason stimulants and depressants change human perceptions of time?
A: The level of activity in the brain of neurotransmitters
Problem: Please answer a question about the following article about Arnold Schwarzenegger:
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.
How many pounds does one of Schwarzenegger's Hummers weigh?
A:
6,300
