Article: Firstly, flanking the open reading frame, all genes contain a regulatory sequence that is required for their expression. In order to be expressed, genes require a promoter sequence. The promoter is recognized and bound by transcription factors and RNA polymerase to initiate transcription.:7.1 A gene can have more than one promoter, resulting in messenger RNAs (mRNA) that differ in how far they extend in the 5' end. Promoter regions have a consensus sequence, however highly transcribed genes have "strong" promoter sequences that bind the transcription machinery well, whereas others have "weak" promoters that bind poorly and initiate transcription less frequently.:7.2 Eukaryotic promoter regions are much more complex and difficult to identify than prokaryotic promoters.:7.3

Question: What results when genes have more than one promoter?
Ans: messenger RNAs (mRNA) that differ in how far they extend in the 5' end

Here is a question about this article: Several solid dielectrics are available, including paper, plastic, glass, mica and ceramic materials. Paper was used extensively in older devices and offers relatively high voltage performance. However, it is susceptible to water absorption, and has been largely replaced by plastic film capacitors. Plastics offer better stability and ageing performance, which makes them useful in timer circuits, although they may be limited to low operating temperatures and frequencies. Ceramic capacitors are generally small, cheap and useful for high frequency applications, although their capacitance varies strongly with voltage and they age poorly. They are broadly categorized as class 1 dielectrics, which have predictable variation of capacitance with temperature or class 2 dielectrics, which can operate at higher voltage. Glass and mica capacitors are extremely reliable, stable and tolerant to high temperatures and voltages, but are too expensive for most mainstream applications. Electrolytic capacitors and supercapacitors are used to store small and larger amounts of energy, respectively, ceramic capacitors are often used in resonators, and parasitic capacitance occurs in circuits wherever the simple conductor-insulator-conductor structure is formed unintentionally by the configuration of the circuit layout.
What is the answer to this question: What is one type of reliable capacitor that is resistant to temperature and voltage changes?
****
So... Glass

The problem: Answer a question about this article:
Public opinion pressured the U.S. government to bring Villa to justice for the raid on Columbus, New Mexico; U.S. President Wilson sent Gen. John J. Pershing and some 5,000 troops into Mexico in an unsuccessful attempt to capture Villa. It was known as the Punitive Expedition. After nearly a year of pursuing Villa, American forces returned to the United States. The American intervention had been limited to the western sierras of Chihuahua. Villa had the advantage of intimately knowing the inhospitable terrain of the Sonoran Desert and the almost impassable Sierra Madre mountains and always managed to stay one step ahead of his pursuers. In 1923 Villa was assassinated by a group of seven gunmen who ambushed him while he was sitting in the back seat of his car in Parral.
In which year was Villa assassinated?
****
The answer: 1923

Problem: Please answer a question about the following article about Portugal:
Travel and tourism continue to be extremely important for Portugal, with visitor numbers forecast to increase significantly in the future.[citation needed] However, the increasing competition from Eastern European destinations continues to develop, with the presence of similar attractions that are often cheaper in countries such as Croatia. Consequently, it has been necessary for the country to focus upon its niche attractions, such as health, nature and rural tourism, to stay ahead of its competitors.
Portuguese tourist numbers are expected to do what in the future?
A: increase

The Third (191923) and Fourth Aliyahs (192429) brought an additional 100,000 Jews to Palestine. Finally, the rise of Nazism and the increasing persecution of Jews in 1930s Europe led to the Fifth Aliyah, with an influx of a quarter of a million Jews. This was a major cause of the Arab revolt of 193639 during which the British Mandate authorities alongside the Zionist militias of Haganah and Irgun killed 5,032 Arabs and wounded 14,760, resulting in over ten percent of the adult male Palestinian Arab population killed, wounded, imprisoned or exiled. The British introduced restrictions on Jewish immigration to Palestine with the White Paper of 1939. With countries around the world turning away Jewish refugees fleeing the Holocaust, a clandestine movement known as Aliyah Bet was organized to bring Jews to Palestine. By the end of World War II, the Jewish population of Palestine had increased to 33% of the total population. On July 22, 1946, Irgun attacked the British administrative headquarters for Palestine, which was housed in the southern wing of the King David Hotel in Jerusalem. 91 people of various nationalities were killed and 46 were injured. The hotel was the site of the central offices of the British Mandatory authorities of Palestine, principally the Secretariat of the Government of Palestine and the Headquarters of the British Armed Forces in Palestine and Transjordan. The attack initially had the approval of the Haganah (the principal Jewish paramilitary group in Palestine). It was conceived as a response to Operation Agatha (a series of widespread raids, including one on the Jewish Agency, conducted by the British authorities) and was the deadliest directed at the British during the Mandate era (19201948).

How many Jews did the Third and Fourth Aliyahs bring to Palestine?
Answer: 100,000

In May 1940, the US requested base rights in Bermuda from the United Kingdom, but British Prime Minister Winston Churchill was initially unwilling to accede to the American request without getting something in return. In September 1940, as part of the Destroyers for Bases Agreement, the UK granted the US base rights in Bermuda. Bermuda and Newfoundland were not originally included in the agreement, but both were added to it, with no war material received by the UK in exchange. One of the terms of the agreement was that the airfield the US Army built would be used jointly by the US and the UK (which it was for the duration of the war, with RAF Transport Command relocating there from Darrell's Island in 1943).
What did the US ask of Britain in May 1940?
base rights in Bermuda
