Here is a question about this article: Some of these estimates also take into account the opportunity cost of investing capital many years before revenues are realized (see Time-value of money). Because of the very long time needed for discovery, development, and approval of pharmaceuticals, these costs can accumulate to nearly half the total expense. A direct consequence within the pharmaceutical industry value chain is that major pharmaceutical multinationals tend to increasingly outsource risks related to fundamental research, which somewhat reshapes the industry ecosystem with biotechnology companies playing an increasingly important role, and overall strategies being redefined accordingly. Some approved drugs, such as those based on re-formulation of an existing active ingredient (also referred to as Line-extensions) are much less expensive to develop.
What is the answer to this question: What accounts for nearly half of the costs to develop drugs?
****
So... opportunity cost of investing capital

The problem: Answer a question about this article:
Prompted by the chaotic torch relays in Western Europe and North America, the president of the International Olympic Committee, Jacques Rogge described the situation as a "crisis" for the organization and stated that any athletes displaying Tibetan flags at Olympic venues could be expelled from the games. though he stopped short of cancelling the relay altogether despite calls to do so by some IOC members. The outcome of the relay influenced the IOC's decision to scrap global relays in future editions of the games.
Athletes wearing what kind of flag at any Olympic venue faced the possibility of expulsion from the Olympics?
****
The answer: Tibetan

Problem: Please answer a question about the following article about Arsenal F.C.:
Arsenal's home colours have been the inspiration for at least three other clubs. In 1909, Sparta Prague adopted a dark red kit like the one Arsenal wore at the time; in 1938, Hibernian adopted the design of the Arsenal shirt sleeves in their own green and white strip. In 1920, Sporting Clube de Braga's manager returned from a game at Highbury and changed his team's green kit to a duplicate of Arsenal's red with white sleeves and shorts, giving rise to the team's nickname of Os Arsenalistas. These teams still wear those designs to this day.
What early team copied the Arsenal's red current color in 1909?
A: Sparta Prague

Question: Read this and answer the question

Another extreme case of impedance matching occurs when using a small loop antenna (usually, but not always, for receiving) at a relatively low frequency where it appears almost as a pure inductor. Resonating such an inductor with a capacitor at the frequency of operation not only cancels the reactance but greatly magnifies the very small radiation resistance of such a loop.[citation needed] This is implemented in most AM broadcast receivers, with a small ferrite loop antenna resonated by a capacitor which is varied along with the receiver tuning in order to maintain resonance over the AM broadcast band

When using a small loop antenna at a low frequency, what may occur?
Answer: impedance matching

Problem: The firm continued to pressure Kelsey and the agency to approve the applicationuntil November 1961, when the drug was pulled off the German market because of its association with grave congenital abnormalities. Several thousand newborns in Europe and elsewhere suffered the teratogenic effects of thalidomide. Though the drug was never approved in the USA, the firm distributed Kevadon to over 1,000 physicians there under the guise of investigational use. Over 20,000 Americans received thalidomide in this "study," including 624 pregnant patients, and about 17 known newborns suffered the effects of the drug.[citation needed]
How many newborns were born with issues due to Kevadon?
The answer is the following: about 17

Input: Article: Greek vocal music extends far back into ancient times where mixed-gender choruses performed for entertainment, celebration and spiritual reasons. Instruments during that period included the double-reed aulos and the plucked string instrument, the lyre, especially the special kind called a kithara. Music played an important role in the education system during ancient times. Boys were taught music from the age of six. Later influences from the Roman Empire, Middle East, and the Byzantine Empire also had effect on Greek music.

Now answer this question: During ancient Greece, at what age were boys taught music?

Output:
six
