Question: Who represents the government body with oversight of the group that issued the report in 1958 in Ann Arbor?

<P0-S0> Executive power is vested, with exceptions and qualifications, in the President. <P0-S1> By law (Section 2.) <P0-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.) <P0-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. <P0-S4> The Constitution empowers the president to ensure the faithful execution of the laws made by Congress and approved by the President. <P0-S5> Congress may itself terminate such appointments, by impeachment, and restrict the president. <P0-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> <P1-S0> On the state level, the city is part of the 18th district in the Michigan Senate, represented by Democrat Rebekah Warren. <P1-S1> In the Michigan House of Representatives, representation is split between the 55th district (northern Ann Arbor, part of Ann Arbor Township, and other surrounding areas, represented by Democrat Adam Zemke), the 53rd district (most of downtown and the southern half of the city, represented by Democrat Jeff Irwin) and the 52nd district (southwestern areas outside Ann Arbor proper and western Washtenaw County, represented by Democrat Gretchen Driskell). <P1-S2> Ann Arbor is part of Michigan's 12th congressional district, represented in Congress by Representative Debbie Dingell, a Democrat. <SEP> <P2-S0> since the university's establishment in the city in 1837, the histories of the university of michigan and ann arbor have been closely linked. <P2-S1> the town became a regional transportation hub in 1839 with the arrival of the michigan central railroad, and a north—south railway connecting ann arbor to toledo and other markets to the south was established in 1878. throughout the 1840s and the 1850s settlers continued to come to ann arbor. <P2-S2> while the earlier settlers were primarily of british ancestry, the newer settlers also consisted of germans, irish, and african-americans. <P2-S3> in 1851, ann arbor was chartered as a city, though the city showed a drop in population during the depression of 1873. it was not until the early 1880s that ann arbor again saw robust growth, with new immigrants coming from greece, italy, russia, and poland. <P2-S4> ann arbor saw increased growth in manufacturing, particularly in milling. <P2-S5> ann arbor's jewish community also grew after the turn of the 20th century, and its first and oldest synagogue, beth israel congregation, was established in 1916. <SEP> <P3-S0> 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. <P3-S1> 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". <P3-S2> 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. <P3-S3> Notable among these was a 75% decline in deaths due to tuberculosis. <P3-S4> A Federal Trade Commission report issued in 1958 attempted to quantify the effect of antibiotic development on American public health. <SEP> <P4-S0> during the 1960s and 1970s, the city gained a reputation as an important center for liberal politics. <P4-S1> ann arbor also became a locus for left-wing activism and served as a hub for the civil-rights movement and anti-vietnam war movement, as well as the student movement. <P4-S2> the first major meetings of the national left-wing campus group students for a democratic society took place in ann arbor in 1960; in 1965, the city was home to the first u.s. teach-in against the vietnam war. <P4-S3> during the ensuing 15 years, many countercultural and new left enterprises sprang up and developed large constituencies within the city. <P4-S4> these influences washed into municipal politics during the early and mid-1970s when three members of the human rights party (hrp) won city council seats on the strength of the student vote. <P4-S5> during their time on the council, hrp representatives fought for measures including pioneering antidiscrimination ordinances, measures decriminalizing marijuana possession, and a rent-control ordinance; many of these remain in effect in modified form. <P4-S6> alongside these liberal and left-wing efforts, a small group of conservative institutions were born in ann arbor. <P4-S7> these include word of god (established in 1967), a charismatic inter-denominational movement; and the thomas more law center (established in 1999), a religious-conservative advocacy group.
