Article: Hebb distinguished between short-term and long-term memory. He postulated that any memory that stayed in short-term storage for a long enough time would be consolidated into a long-term memory. Later research showed this to be false. Research has shown that direct injections of cortisol or epinephrine help the storage of recent experiences. This is also true for stimulation of the amygdala. This proves that excitement enhances memory by the stimulation of hormones that affect the amygdala. Excessive or prolonged stress (with prolonged cortisol) may hurt memory storage. Patients with amygdalar damage are no more likely to remember emotionally charged words than nonemotionally charged ones. The hippocampus is important for explicit memory. The hippocampus is also important for memory consolidation. The hippocampus receives input from different parts of the cortex and sends its output out to different parts of the brain also. The input comes from secondary and tertiary sensory areas that have processed the information a lot already. Hippocampal damage may also cause memory loss and problems with memory storage. This memory loss includes, retrograde amnesia which is the loss of memory for events that occurred shortly before the time of brain damage.

Question: Which drugs seemed to help someone remember earlier events?
Ans: cortisol or epinephrine


Here is a question about this article: Washington University spent its first half century in downtown St. Louis bounded by Washington Ave., Lucas Place, and Locust Street. By the 1890s, owing to the dramatic expansion of the Manual School and a new benefactor in Robert Brookings, the University began to move west. The University Board of Directors began a process to find suitable ground and hired the landscape architecture firm Olmsted, Olmsted & Eliot of Boston. A committee of Robert S. Brookings, Henry Ware Eliot, and William Huse found a site of 103 acres (41.7 ha) just beyond Forest Park, located west of the city limits in St. Louis County. The elevation of the land was thought to resemble the Acropolis and inspired the nickname of "Hilltop" campus, renamed the Danforth campus in 2006 to honor former chancellor William H. Danforth.
What is the answer to this question: When did Washington University begin to expand west?
****
So... the 1890s


The problem: Answer a question about this article:
Hydrogen's rarer isotopes also each have specific applications. Deuterium (hydrogen-2) is used in nuclear fission applications as a moderator to slow neutrons, and in nuclear fusion reactions. Deuterium compounds have applications in chemistry and biology in studies of reaction isotope effects. Tritium (hydrogen-3), produced in nuclear reactors, is used in the production of hydrogen bombs, as an isotopic label in the biosciences, and as a radiation source in luminous paints.
What isotope is used in nuclear fission?
****
The answer: Deuterium


Problem: Please answer a question about the following article about Sino-Tibetan relations during the Ming dynasty:
A. Tom Grunfeld says that Tsongkhapa claimed ill health in his refusal to appear at the Ming court, while Rossabi adds that Tsongkhapa cited the "length and arduousness of the journey" to China as another reason not to make an appearance. This first request by the Ming was made in 1407, but the Ming court sent another embassy in 1413, this one led by the eunuch Hou Xian (候顯; fl. 1403–1427), which was again refused by Tsongkhapa. Rossabi writes that Tsongkhapa did not want to entirely alienate the Ming court, so he sent his disciple Chosrje Shākya Yeshes to Nanjing in 1414 on his behalf, and upon his arrival in 1415 the Yongle Emperor bestowed upon him the title of "State Teacher"—the same title earlier awarded the Phagmodrupa ruler of Tibet. The Xuande Emperor (r. 1425–1435) even granted this disciple Chosrje Shākya Yeshes the title of a "King" (王). This title does not appear to have held any practical meaning, or to have given its holder any power, at Tsongkhapa's Ganden Monastery. Wylie notes that this—like the Karma Kargyu—cannot be seen as a reappointment of Mongol Yuan offices, since the Gelug school was created after the fall of the Yuan dynasty.
When did the Ming court send a second request to Tsongkhapa?
A: 1413


Question: Read this and answer the question

A patent is a form of right granted by the government to an inventor, giving the owner the right to exclude others from making, using, selling, offering to sell, and importing an invention for a limited period of time, in exchange for the public disclosure of the invention. An invention is a solution to a specific technological problem, which may be a product or a process and generally has to fulfil three main requirements: it has to be new, not obvious and there needs to be an industrial applicability.:17

How many requirements does an invention need to fulfill for a patent?
Answer: three


To other analysts the delay between CRA rule changes (in 1995) and the explosion of subprime lending is not surprising, and does not exonerate the CRA. They contend that there were two, connected causes to the crisis: the relaxation of underwriting standards in 1995 and the ultra-low interest rates initiated by the Federal Reserve after the terrorist attack on September 11, 2001. Both causes had to be in place before the crisis could take place. Critics also point out that publicly announced CRA loan commitments were massive, totaling $4.5 trillion in the years between 1994 and 2007. They also argue that the Federal Reserve’s classification of CRA loans as “prime” is based on the faulty and self-serving assumption that high-interest-rate loans (3 percentage points over average) equal “subprime” loans.
When did CRA make rule changes to relax underwriting standards?
1995
