Which best describes nixon’s assessment of how americans felt about the vietnam war when he became president in 1969?

President Nixon overestimated people's support for his Vietnam policies and underestimated opposition to continuing the war.

Richard Nixon had campaigned for the presidency by appealing to what he called "The Silent Majority" of American citizens -- the everyday, middle-class, working folks who were not part of the anti-war protests that had been happening in the country.  On November 3, 1969, during his first year in office, President Nixon called on that "silent majority" in a major radio and television address.  In response to continuing war protests, Nixon urged solidarity in support of the war effort in Vietnam War effort, saying that the United States was “going to keep our commitment in Vietnam.”  He pledged that US forces would keep fighting until an honorable peace was achieved or until the South Vietnamese were able to defend themselves without US help.

Nixon's urgings did not stop the war protests.  In fact, the largest anti-war protest in US history then took place on November 15, 1969.  The Moratorium to End the War in Vietnam, which had staged teach-ins and demonstrations across the country in October, held a massive march and rally in Washington, DC, which was attended by half a million protesters.

the underground railroad (apocope of the metropolitan railroad) is a system of urban trains located within a city and its metropolitan area. it is characterized for being a massive transport of passengers in the big cities, uniting diverse zones and their environs, with high capacity and frequency and in segregated form to other systems of transport. metropolitan railroads are built underground or on the surface, although most systems use mixed models where sections are combined in both modalities.

1 - as a result, the metro tends to reduce car travel for two reasons: first, due to the greater transfer of users from the car and, second, due to the reduction in the acquisition of cars in homes located in sectors near the stations of the metro.

2 -the metro allows to contribute effectively to the achievement of all the objectives of an urban development policy: it improves the efficiency of the city's economy by reducing travel costs and also generates a higher level of activities in the city center, taking advantage of of the agglomeration economies.

3 -it is a clean means of transport, since it uses renewable energy (usually electricity), taking care of the environment and avoiding excessive pollution.
