QUES: 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).

What causes rats to underestimate dopamine levels?

QUES: While other companies were moving on to 32-bit systems, Rare and Nintendo proved that the SNES was still a strong contender in the market. In November 1994, Rare released Donkey Kong Country, a platform game featuring 3D models and textures pre-rendered on SGI workstations. With its detailed graphics, fluid animation and high-quality music, Donkey Kong Country rivaled the aesthetic quality of games that were being released on newer 32-bit CD-based consoles. In the last 45 days of 1994, the game sold 6.1 million units, making it the fastest-selling video game in history to that date. This game sent a message that early 32-bit systems had little to offer over the SNES, and helped make way for the more advanced consoles on the horizon.

QUES: Whites (mainly of Afrikaner, German, British and Portuguese origin) make up between 4.0 and 7.0% of the population. Although their percentage of population is decreasing due to emigration and lower birth rates they still form the second-largest population of European ancestry, both in terms of percentage and actual numbers, in Sub-Saharan Africa (after South Africa). The majority of Namibian whites and nearly all those who are mixed race speak Afrikaans and share similar origins, culture, and religion as the white and coloured populations of South Africa. A large minority of whites (around 30,000) trace their family origins back to the German settlers who colonized Namibia prior to the British confiscation of German lands after World War One, and they maintain German cultural and educational institutions. Nearly all Portuguese settlers came to the country from the former Portuguese colony of Angola. The 1960 census reported 526,004 persons in what was then South-West Africa, including 73,464 whites (14%).
