Here is a question about this article: According to Y chromosome studies by Sanchez et al. (2005), Cruciani et al. (2004, 2007), the Somalis are paternally closely related to other Afro-Asiatic-speaking groups in Northeast Africa. Besides comprising the majority of the Y-DNA in Somalis, the E1b1b1a (formerly E3b1a) haplogroup also makes up a significant proportion of the paternal DNA of Ethiopians, Sudanese, Egyptians, Berbers, North African Arabs, as well as many Mediterranean populations. Sanchez et al. (2005) observed the M78 subclade of E1b1b in about 77% of their Somali male samples. According to Cruciani et al. (2007), the presence of this subhaplogroup in the Horn region may represent the traces of an ancient migration from Egypt/Libya. After haplogroup E1b1b, the second most frequently occurring Y-DNA haplogroup among Somalis is the West Asian haplogroup T (M70). It is observed in slightly more than 10% of Somali males. Haplogroup T, like haplogroup E1b1b, is also typically found among populations of Northeast Africa, North Africa, the Near East and the Mediterranean.
What is the answer to this question: What language group speakers are ethnic Somalis closely related to?
****
So... Afro-Asiatic


The problem: Answer a question about this article:
Some of the best-known traditions, including carnal parades and masquerade balls, were first recorded in medieval Italy. The carnival of Venice was, for a long time, the most famous carnival (although Napoleon abolished it in 1797 and only in 1979 was the tradition restored). From Italy, Carnival traditions spread to Spain, Portugal and France and from France to New France in North America. From Spain and Portugal it spread with colonization to the Caribbean and Latin America. In the early 19th century in the German Rhineland and Southern Netherlands, the weakened medieval tradition also revive. Continuously in the 18th and 19th centuries CE, as part of the annual Saturnalia abuse of the carnival in Rome, rabbis of the ghetto were forced to march through the city streets wearing foolish guise, jeered upon and pelted by a variety of missiles from the crowd. A petition of the Jewish community of Rome sent in 1836 to Pope Gregory XVI to stop the annual anti-semitic Saturnalia abuse got a negation: “It is not opportune to make any innovation.”
What city's carnival was the most famous for a long time?
****
The answer: Venice


Problem: Please answer a question about the following article about BBC Television:
While the "footprint" of the Astra 2D satellite was smaller than that of Astra 2A, from which it was previously broadcast encrypted, it meant that viewers with appropriate equipment were able to receive BBC channels "free-to-air" over much of Western Europe. Consequently, some rights concerns have needed to be resolved with programme providers such as Hollywood studios and sporting organisations, which have expressed concern about the unencrypted signal leaking out. This led to some broadcasts being made unavailable on the Sky Digital platform, such as Scottish Premier League and Scottish Cup football, while on other platforms such broadcasts were not disrupted. Later, when rights contracts were renewed, this problem was resolved.
With the right tools, what area could get free BBC broadcasts from Astra 2D?
A: Western Europe


Question: Read this and answer the question

Including Kerry, the Democratic primary race had 10 candidates, including attorney Paul J. Sheehy, State Representative Anthony R. DiFruscia, John J. Desmond and Robert B. Kennedy. Kerry ran a "very expensive, sophisticated campaign", financed by out-of-state backers and supported by many young volunteers. DiFruscia's campaign headquarters shared the same building as Kerry's. On the eve of the September 19 primary, police found Kerry's younger brother Cameron and campaign field director Thomas J. Vallely, breaking into where the building's telephone lines were located. They were arrested and charged with "breaking and entering with the intent to commit grand larceny", but the charges were dropped a year later. At the time of the incident, DiFruscia alleged that the two were trying to disrupt his get-out-the vote efforts. Vallely and Cameron Kerry maintained that they were only checking their own telephone lines because they had received an anonymous call warning that the Kerry lines would be cut.

Who did Kerry share a campaign headquarters with?
Answer: Anthony R. DiFruscia


Problem: The first elevator shaft preceded the first elevator by four years. Construction for Peter Cooper's Cooper Union Foundation building in New York began in 1853. An elevator shaft was included in the design, because Cooper was confident that a safe passenger elevator would soon be invented. The shaft was cylindrical because Cooper thought it was the most efficient design. Later, Otis designed a special elevator for the building. Today the Otis Elevator Company, now a subsidiary of United Technologies Corporation, is the world's largest manufacturer of vertical transport systems.
The Otis Elevator Company is today a subsidiary of what major corporation?
The answer is the following: United Technologies Corporation


Input: Article: There has, however, been interest among railroad operators in returning to DC use at higher voltages than previously used. At the same voltage, DC often has less loss than AC, and for this reason high-voltage direct current is already used on some bulk power transmission lines. DC avoids the electromagnetic radiation inherent with AC, and on a railway this also reduces interference with signalling and communications and mitigates hypothetical EMF risks. DC also avoids the power factor problems of AC. Of particular interest to railroading is that DC can supply constant power with a single ungrounded wire. Constant power with AC requires three-phase transmission with at least two ungrounded wires. Another important consideration is that mains-frequency 3-phase AC must be carefully planned to avoid unbalanced phase loads. Parts of the system are supplied from different phases on the assumption that the total loads of the 3 phases will even out. At the phase break points between regions supplied from different phases, long insulated supply breaks are required to avoid them being shorted by rolling stock using more than one pantograph at a time. A few railroads have tried 3-phase but its substantial complexity has made single-phase standard practice despite the interruption in power flow that occurs twice every cycle. An experimental 6 kV DC railway was built in the Soviet Union.

Now answer this question: Which type of power does require three-phase transmission?

Output:
AC
