Prior to the 20th century drugs were generally produced by small scale manufacturers with little regulatory control over manufacturing or claims of safety and efficacy. To the extent that such laws did exist, enforcement was lax. In the United States, increased regulation of vaccines and other biological drugs was spurred by tetanus outbreaks and deaths caused by the distribution of contaminated smallpox vaccine and diphtheria antitoxin. The Biologics Control Act of 1902 required that federal government grant premarket approval for every biological drug and for the process and facility producing such drugs. This was followed in 1906 by the Pure Food and Drugs Act, which forbade the interstate distribution of adulterated or misbranded foods and drugs. A drug was considered misbranded if it contained alcohol, morphine, opium, cocaine, or any of several other potentially dangerous or addictive drugs, and if its label failed to indicate the quantity or proportion of such drugs. The government's attempts to use the law to prosecute manufacturers for making unsupported claims of efficacy were undercut by a Supreme Court ruling restricting the federal government's enforcement powers to cases of incorrect specification of the drug's ingredients.
What Act forbade misbranded drugs?
A: Pure Food and Drugs Act

In 2002, the Musharraf-led government took a firm stand against the jihadi organizations and groups promoting extremism, and arrested Maulana Masood Azhar, head of the Jaish-e-Mohammed, and Hafiz Muhammad Saeed, chief of the Lashkar-e-Taiba, and took dozens of activists into custody. An official ban was imposed on the groups on 12 January. Later that year, the Saudi born Zayn al-Abidn Muhammed Hasayn Abu Zubaydah was arrested by Pakistani officials during a series of joint U.S.-Pakistan raids. Zubaydah is said to have been a high-ranking al-Qaeda official with the title of operations chief and in charge of running al-Qaeda training camps. Other prominent al-Qaeda members were arrested in the following two years, namely Ramzi bin al-Shibh, who is known to have been a financial backer of al-Qaeda operations, and Khalid Sheikh Mohammed, who at the time of his capture was the third highest-ranking official in al-Qaeda and had been directly in charge of the planning for the 11 September attacks.
Which third-highest-ranking al-Qaeda officer was captured?

Zinc serves a purely structural role in zinc fingers, twists and clusters. Zinc fingers form parts of some transcription factors, which are proteins that recognize DNA base sequences during the replication and transcription of DNA. Each of the nine or ten Zn2+ ions in a zinc finger helps maintain the finger's structure by coordinately binding to four amino acids in the transcription factor. The transcription factor wraps around the DNA helix and uses its fingers to accurately bind to the DNA sequence.
What are proteins that druing replication and transcription of DNA, recognize base DNA?
A: transcription factors,

Hack Wilson set a record of 56 home-runs and 190 runs-batted-in in 1930, breaking Lou Gehrig's MLB record of 176 RBI. (In 1999, a long-lost extra RBI mistakenly credited to Charlie Grimm had been found by Cooperstown researcher Cliff Kachline and verified by historian Jerome Holtzman, increasing the record number to 191.) As of 2014 the record still stands, with no serious threats coming since Gehrig (184) and Hank Greenberg (183) in the same era. The closest anyone has come to the mark in the last 75 years was Manny Ramirez's 165 RBI in 1999. In addition to the RBI record, Wilson 56 home-runs stood as the National League record until 1998, when Sammy Sosa and Mark McGwire hit 66 and 70, respectively. Wilson was named "Most Useful" player that year by the Baseball Writers' Association of America, as the official N.L. Most Valuable Player Award was not awarded until the next season.
What was Wilson named by the Baseball Writer's Association of America? 
A:
"Most Useful" player
