Here is a question about this article: Roosevelt Boulevard and the Roosevelt Expressway (U.S. 1) connect Northeast Philadelphia with Center City. Woodhaven Road (Route 63), built in 1966, and Cottman Avenue (Route 73) serve the neighborhoods of Northeast Philadelphia, running between Interstate 95 and the Roosevelt Boulevard (U.S. 1). The Fort Washington Expressway (Route 309) extends north from the city's northern border, serving Montgomery County and Bucks County. U.S. 30, extending east-west from West Philadelphia to Lancaster, is known as Lancaster Avenue throughout most of the city and through the adjacent Main Line suburbs.
What is the answer to this question: What is US-30 also known as?
****
So... Lancaster Avenue

The problem: Answer a question about this article:
Not all introduced species are invasive, nor all invasive species deliberately introduced. In cases such as the zebra mussel, invasion of US waterways was unintentional. In other cases, such as mongooses in Hawaii, the introduction is deliberate but ineffective (nocturnal rats were not vulnerable to the diurnal mongoose). In other cases, such as oil palms in Indonesia and Malaysia, the introduction produces substantial economic benefits, but the benefits are accompanied by costly unintended consequences.
What animal unintentionally invaded the US waterways?
****
The answer: the zebra mussel

Problem: Please answer a question about the following article about George VI:
On the day of the abdication, the Oireachtas, the parliament of the Irish Free State, removed all direct mention of the monarch from the Irish constitution. The next day, it passed the External Relations Act, which gave the monarch limited authority (strictly on the advice of the government) to appoint diplomatic representatives for Ireland and to be involved in the making of foreign treaties. The two acts made the Irish Free State a republic in essence without removing its links to the Commonwealth.
What did the Oireachtas remove from the Irish constitution?
A: all direct mention of the monarch

Question: Read this and answer the question

The independence of the ECB is instrumental in maintaining price stability. Not only must the bank not seek influence, but EU institutions and national governments are bound by the treaties to respect the ECB's independence. To offer some accountability, the ECB is bound to publish reports on its activities and has to address its annual report to the European Parliament, the European Commission, the Council of the European Union and the European Council. The European Parliament also gets to question and then issue its opinion on candidates to the executive board.

Who gets to interview and question prospective board members?
Answer: The European Parliament

Problem: Insects (from Latin insectum, a calque of Greek [entomon], "cut into sections") are a class of invertebrates within the arthropod phylum that have a chitinous exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. They are the most diverse group of animals on the planet, including more than a million described species and representing more than half of all known living organisms. The number of extant species is estimated at between six and ten million, and potentially represent over 90% of the differing animal life forms on Earth. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, a habitat dominated by another arthropod group, crustaceans.
What type of exoskeleton do insects have?
The answer is the following: chitinous

Input: Article: Providing sufficient base drive current is a key problem in the use of bipolar transistors as switches. The transistor provides current gain, allowing a relatively large current in the collector to be switched by a much smaller current into the base terminal. The ratio of these currents varies depending on the type of transistor, and even for a particular type, varies depending on the collector current. In the example light-switch circuit shown, the resistor is chosen to provide enough base current to ensure the transistor will be saturated.

Now answer this question: What determines the current ratio in transistors?

Output:
the type of transistor
