Here is a question about this article: Digital-RGB LEDs are RGB LEDs that contain their own "smart" control electronics. In addition to power and ground, these provide connections for data-in, data-out, and sometimes a clock or strobe signal. These are connected in a daisy chain, with the data in of the first LED sourced by a microprocessor, which can control the brightness and color of each LED independently of the others. They are used where a combination of maximum control and minimum visible electronics are needed such as strings for Christmas and LED matrices. Some even have refresh rates in the kHz range, allowing for basic video applications.
What is the answer to this question: How are Digital-RGB LED strobe signals connected?
****
So... in a daisy chain

Problem: Please answer a question about the following article about Muammar Gaddafi:
Libya's economy witnessed increasing privatization; although rejecting the socialist policies of nationalized industry advocated in The Green Book, government figures asserted that they were forging "people's socialism" rather than capitalism. Gaddafi welcomed these reforms, calling for wide-scale privatization in a March 2003 speech. In 2003, the oil industry was largely sold to private corporations, and by 2004, there was $40 billion of direct foreign investment in Libya, a sixfold rise over 2003. Sectors of Libya's population reacted against these reforms with public demonstrations, and in March 2006, revolutionary hard-liners took control of the GPC cabinet; although scaling back the pace of the changes, they did not halt them. In 2010, plans were announced that would have seen half the Libyan economy privatized over the following decade. While there was no accompanying political liberalization, with Gaddafi retaining predominant control, in March 2010, the government devolved further powers to the municipal councils. Rising numbers of reformist technocrats attained positions in the country's governance; best known was Gaddafi's son and heir apparent Saif al-Islam Gaddafi, who was openly critical of Libya's human rights record. He led a group who proposed the drafting of the new constitution, although it was never adopted, and in October 2009 was appointed to head the PSLC. Involved in encouraging tourism, Saif founded several privately run media channels in 2008, but after criticising the government they were nationalised in 2009. In October 2010, Gaddafi apologized to African leaders on behalf of Arab nations for their involvement in the African slave trade.
As of October 2009, who was the head of the PSLC?
A: Saif al-Islam Gaddafi

Problem: The war had removed Bermuda's primary trading partners, the American colonies, from the empire, and dealt a harsh blow to Bermuda's merchant shipping trade. This also suffered due to the deforestation of Bermuda, as well as the advent of metal ships and steam propulsion, for which it did not have raw materials. During the course of the following War of 1812, the primary market for Bermuda's salt disappeared as the Americans developed their own sources. Control of the Turks had passed to the Bahamas in 1819.
Who was Bermuda's main trading partner before the war?
The answer is the following: American colonies


Input: Article: Teenage alcohol drug use is currently at an all-time low. Out of a polled body of students, 4.4% of 8th graders reported having been on at least one occasion been drunk within the previous month; for 10th graders, the number was 13.7%, and for 12th graders, 25%. More drastically, cigarette smoking has become a far less prevalent activity among American middle- and high-school students; in fact, a greater number of teens now smoke marijuana than smoke cigarettes, with one recent study showing a respective 15.2% versus 11.7% of surveyed students. Recent studies have shown that male late adolescents are far more likely to smoke cigarettes rather than females. The study indicated that there was a discernible gender difference in the prevalence of smoking among the students. The finding of the study show that more males than females began smoking when they were in primary and high schools whereas most females started smoking after high school. This may be attributed to recent changing social and political views towards marijuana; issues such as medicinal use and legalization have tended towards painting the drug in a more positive light than historically, while cigarettes continue to be vilified due to associated health risks.

Now answer this question: Is teenage alcohol drug use at al all-time high or low?

Output:
