Article: Federal law originates with the Constitution, which gives Congress the power to enact statutes for certain limited purposes like regulating interstate commerce. The United States Code is the official compilation and codification of the general and permanent federal statutes. Many statutes give executive branch agencies the power to create regulations, which are published in the Federal Register and codified into the Code of Federal Regulations. Regulations generally also carry the force of law under the Chevron doctrine. Many lawsuits turn on the meaning of a federal statute or regulation, and judicial interpretations of such meaning carry legal force under the principle of stare decisis.

Question: What gives Congress limited power to enact statutes?
Ans: the Constitution

Article: Due to the often political and cultural contours of blackness in the United States, the notion of blackness can also be extended to non-black people. Toni Morrison once described Bill Clinton as the first black President of the United States, because, as she put it, he displayed "almost every trope of blackness". Christopher Hitchens was offended by the notion of Clinton as the first black president, noting, "Mr Clinton, according to Toni Morrison, the Nobel Prize-winning novelist, is our first black President, the first to come from the broken home, the alcoholic mother, the under-the-bridge shadows of our ranking systems. Thus, we may have lost the mystical power to divine diabolism, but we can still divine blackness by the following symptoms: broken homes, alcoholic mothers, under-the-bridge habits and (presumable from the rest of [Arthur] Miller's senescent musings) the tendency to sexual predation and to shameless perjury about same." Some black activists were also offended, claiming that Clinton used his knowledge of black culture to exploit black people for political gain as no other president had before, while not serving black interests. They cite the lack of action during the Rwandan Genocide and his welfare reform, which Larry Roberts said had led to the worst child poverty since the 1960s. Others cited that the number of black people in jail increased during his administration.

Question: Why were people offended by this comment?
Ans: Clinton used his knowledge of black culture to exploit black people for political gain

Article: A 2009 Cochrane review concluded that thiazide antihypertensive drugs reduce the risk of death (RR 0.89), stroke (RR 0.63), coronary heart disease (RR 0.84), and cardiovascular events (RR 0.70) in people with high blood pressure. In the ensuring years other classes of antihypertensive drug were developed and found wide acceptance in combination therapy, including loop diuretics (Lasix/furosemide, Hoechst Pharmaceuticals, 1963), beta blockers (ICI Pharmaceuticals, 1964) ACE inhibitors, and angiotensin receptor blockers. ACE inhibitors reduce the risk of new onset kidney disease [RR 0.71] and death [RR 0.84] in diabetic patients, irrespective of whether they have hypertension.

Question: In what year was thiazide antihypertensive drugs shown to help those with heart problems?
