Here is a question about this article: Although the number of base-pairs of DNA in the human genome has been known since the 1960s, the estimated number of genes has changed over time as definitions of genes, and methods of detecting them have been refined. Initial theoretical predictions of the number of human genes were as high as 2,000,000. Early experimental measures indicated there to be 50,000100,000 transcribed genes (expressed sequence tags). Subsequently, the sequencing in the Human Genome Project indicated that many of these transcripts were alternative variants of the same genes, and the total number of protein-coding genes was revised down to ~20,000 with 13 genes encoded on the mitochondrial genome. Of the human genome, only 12% consists of protein-coding genes, with the remainder being 'noncoding' DNA such as introns, retrotransposons, and noncoding RNAs.
What is the answer to this question: Since when has the number of base pairs of DNA in the human genome been known?
****
So... the 1960s

The problem: Answer a question about this article:
Franklin S. Harris was appointed the university's president in 1921. He was the first BYU president to have a doctoral degree. Harris made several important changes to the school, reorganizing it into a true university, whereas before, its organization had remnants of the Academy days. At the beginning of his tenure, the school was not officially recognized as a university by any accreditation organization. By the end of his term, the school was accredited under all major accrediting organizations at the time. He was eventually replaced by Howard S. McDonald, who received his doctorate from the University of California. When he first received the position, the Second World War had just ended, and thousands of students were flooding into BYU. By the end of his stay, the school had grown nearly five times to an enrollment of 5,440 students. The university did not have the facilities to handle such a large influx, so he bought part of an Air Force Base in Ogden, Utah and rebuilt it to house some of the students. The next president, Ernest L. Wilkinson, also oversaw a period of intense growth, as the school adopted an accelerated building program. Wilkinson was responsible for the building of over eighty structures on the campus, many of which still stand. During his tenure, the student body increased six times, making BYU the largest private school at the time. The quality of the students also increased, leading to higher educational standards at the school. Finally, Wilkinson reorganized the LDS Church units on campus, with ten stakes and over 100 wards being added during his administration.
Which president was responsible for the most amount of growth to the campus?
****
The answer: Ernest L. Wilkinson

Problem: Please answer a question about the following article about Predation:
Having small population size is a characteristic almost universally inherent to apex predators, humans and dogs by far the most blatant exceptions. Low numbers wouldn't be a problem for apex predators if there was an abundance of prey and no competition or niche overlap, a scenario that is rarely, if ever, encountered in the wild. The competitive exclusion principle states that if two species' ecological niches overlap, there is a very high likelihood of competition as both species are in direct competition for the same resources. This factor alone could lead to the extirpation of one or both species, but is compounded by the added factor of prey abundance.
Which principle states that if two species ecologicl niches/ overlap, both species are likely to be in competition with one another?
A: competitive exclusion principle

Question: Read this and answer the question

In July 2010, Governor Chris Christie announced that a state takeover of the city and local government "was imminent". Comparing regulations in Atlantic City to an "antique car", Atlantic City regulatory reform is a key piece of Gov. Chris Christie's plan, unveiled on July 22, to reinvigorate an industry mired in a four-year slump in revenue and hammered by fresh competition from casinos in the surrounding states of Delaware, Pennsylvania, Connecticut, and more recently, Maryland. In January 2011, Chris Christie announced the Atlantic City Tourism District, a state-run district encompassing the boardwalk casinos, the marina casinos, the Atlantic City Outlets, and Bader Field. Fairleigh Dickinson University's PublicMind poll surveyed New Jersey voters' attitudes on the takeover. The February 16, 2011 survey showed that 43% opposed the measure while 29% favored direct state oversight. Interestingly, the poll also found that even South Jersey voters expressed opposition to the plan; 40% reported they opposed the measure and 37% reported they were in favor of it.

What was the name of the district that would encompass the boardwalk casinos, the marina casinos, the Atlantic City Outlets, and Bader Field?
Answer: Atlantic City Tourism District

Problem: The fighter aircraft of the USAF are small, fast, and maneuverable military aircraft primarily used for air-to-air combat. Many of these fighters have secondary ground-attack capabilities, and some are dual-roled as fighter-bombers (e.g., the F-16 Fighting Falcon); the term "fighter" is also sometimes used colloquially for dedicated ground-attack aircraft. Other missions include interception of bombers and other fighters, reconnaissance, and patrol. The F-16 is currently used by the USAF Air Demonstration squadron, the Thunderbirds, while a small number of both man-rated and non-man-rated F-4 Phantom II are retained as QF-4 aircraft for use as Full Scale Aerial Targets (FSAT) or as part of the USAF Heritage Flight program. These extant QF-4 aircraft are being replaced in the FSAT role by early model F-16 aircraft converted to QF-16 configuration. The USAF has 2,025 fighters in service as of September 2012.
What is the primary function of the USAF fighter aircraft?
The answer is the following: air-to-air combat

Input: Article: Modern electrification systems take AC energy from a power grid which is delivered to a locomotive and converted to a DC voltage to be used by traction motors. These motors may either be DC motors which directly use the DC or they may be 3-phase AC motors which require further conversion of the DC to 3-phase AC (using power electronics). Thus both systems are faced with the same task: converting and transporting high-voltage AC from the power grid to low-voltage DC in the locomotive. Where should this conversion take place and at what voltage and current (AC or DC) should the power flow to the locomotive? And how does all this relate to energy-efficiency? Both the transmission and conversion of electric energy involve losses: ohmic losses in wires and power electronics, magnetic field losses in transformers and smoothing reactors (inductors). Power conversion for a DC system takes place mainly in a railway substation where large, heavy, and more efficient hardware can be used as compared to an AC system where conversion takes place aboard the locomotive where space is limited and losses are significantly higher. Also, the energy used to blow air to cool transformers, power electronics (including rectifiers), and other conversion hardware must be accounted for.

Now answer this question: What is the main action AC and DC systems have to deal with?

Output:
converting and transporting
