Question: When was the first African American elected to the body providing oversight of the commission that issued the report in 1958?

<P0-S0> estonia has pursued the development of the e-state and e-government. <P0-S1> internet voting is used in elections in estonia. <P0-S2> the first internet voting took place in the 2005 local elections and the first in a parliamentary election was made available for the 2007 elections, in which 30,275 individuals voted over the internet. <P0-S3> voters have a chance to invalidate their electronic vote in traditional elections, if they wish to. <P0-S4> in 2009 in its eighth worldwide press freedom index, reporters without borders ranked estonia sixth out of 175 countries. <P0-S5> in the first ever state of world liberty index report, estonia was ranked first out of 159 countries. <SEP> <P1-S0> walthourville is a city in liberty county, georgia, united states. <P1-S1> when it was incorporated in 1974, it had a government entirely composed of women; and in 1978 it elected carrie kent, the first african-american woman mayor in georgia history. <P1-S2> walthourville is a part of the hinesville-fort stewart metropolitan statistical area. <P1-S3> the population was 4,111 at the 2010 census. <SEP> <P2-S0> As a result of these measures, blacks acquired the right to vote across the Southern states. <P2-S1> In several states (notably Mississippi and South Carolina), blacks were the majority of the population. <P2-S2> By forming coalitions with pro-Union whites, Republicans took control of the state legislatures. <P2-S3> At the time, state legislatures elected the members of the US Senate. <P2-S4> During Reconstruction, only the state legislature of Mississippi elected any black senators. <P2-S5> On February 25, 1870, Hiram Rhodes Revels was seated as the first black member of the Senate, while Blanche Bruce, also of Mississippi, seated in 1875, was the second. <P2-S6> Revels was the first black member of the Congress overall. <SEP> <P3-S0> Executive power is vested, with exceptions and qualifications, in the President. <P3-S1> By law (Section 2.) <P3-S2> the president becomes the Commander in Chief of the Army and Navy, Militia of several states when called into service, has power to make treaties and appointments to office "with the Advice and Consent of the Senate," receive Ambassadors and Public Ministers, and "take care that the laws be faithfully executed" (Section 3.) <P3-S3> By using these words, the Constitution does not require the president to personally enforce the law; rather, officers subordinate to the president may perform such duties. <P3-S4> The Constitution empowers the president to ensure the faithful execution of the laws made by Congress and approved by the President. <P3-S5> Congress may itself terminate such appointments, by impeachment, and restrict the president. <P3-S6> Bodies such as the War Claims Commission, the Interstate Commerce Commission and the Federal Trade Commission—all quasi-judicial—often have direct Congressional oversight. <SEP> <P4-S0> A Federal Trade Commission report issued in 1958 attempted to quantify the effect of antibiotic development on American public health. <P4-S1> The report found that over the period 1946-1955, there was a 42% drop in the incidence of diseases for which antibiotics were effective and only a 20% drop in those for which antibiotics were not effective. <P4-S2> The report concluded that "it appears that the use of antibiotics, early diagnosis, and other factors have limited the epidemic spread and thus the number of these diseases which have occurred". <P4-S3> The study further examined mortality rates for eight common diseases for which antibiotics offered effective therapy (syphilis, tuberculosis, dysentery, scarlet fever, whooping cough, meningococcal infections, and pneumonia), and found a 56% decline over the same period. <P4-S4> Notable among these was a 75% decline in deaths due to tuberculosis.
