1- The correct answer is B, as one result of the Great Society was that the lives of many underprivileged Americans improved.

The Great Society was a set of US national reform programs announced by President Lyndon B. Johnson for the first time in a speech at Ohio University on May 7, 1964 and more fully illustrated on May 22, 1964 at the University of Michigan. These reform programs were subsequently presented to the Congress of the United States and largely approved during the 1960s, thanks to the consent of its supporters of the Democratic Party.

Two main goals of social reforms were the elimination of poverty and racial injustice. During this period new large spending programs were launched in the fields of education, medical care, urban problems and transport. Johnson’s “Great Society” was linked, in its objectives and policies, to President Franklin Delano Roosevelt’s New Deal program.

Some proposals of the Great Society resumed initiatives contained in the New Frontier program, interrupted by the tragic death of President John F. Kennedy. Johnson’s success in promoting and endorsing his reforms depended on his considerable congressional political influence, his persuasion, and the favorable historical circumstances resulting from the 1964 presidential elections, which allowed the Democratic Party to dominate Congress and to elect the House of Representatives with the largest number of exponents of the liberal current since 1938.

The evolution of the Vietnam war and the massive involvement of the American military machine in the conflict, however, partly undermined the success of the “Great Society” program. Growing, huge expenditures for the continuation of the war made more difficult to finance the reform programs. Representatives of the Democratic Party against the war in Vietnam complained that military spending decisively stifled the Great Society program. On the whole, however, despite growing political and economic difficulties, which forced the administration to eliminate or reduce the financing of some projects, President Johnson managed to activate a series of programs of great importance, including Medicare, Medicaid, the Older Americans Act and the federal education funding, which are still active.

2- The correct answer is C, as the Immigration and Nationality Act of 1965 was necessary because the previous existing American immigration policies were discriminatory.

On October 3, 1965, President Lyndon B. Johnson signed the law into effect, saying: “The [old] system violates the basic principle of American democracy, the principle according to which the valuation and reward of each man should be established on the basis of his merits as a man. It has been anti-American in the highest sense, because it has been unfaithful to the faith that led thousands to these shores, even before we were a country. ”

If you become skillful at basketball because your friends encourage you to play and you have practiced a lot, your behavior is influenced primarily by __________. if you are good at basketball mainly because you are very tall, as have been all of the members of your family for generations, your behavior is influenced primarily by __________.

[ad_1]

Answer:

The answer is C. In order to carefully control conditions and confirm or disconfirm a hypothesis about the causes of behavior, one must perform an experiment.

Explanation:

Experimental research allows the researcher to control all the variables in order to create the conditions that can confirm or disconfirm a hypothesis. This method aimes to establish a relation of causality between two variables, which means that one variable is generated and determined by the other; this is posible because all of the other variables that can influence it have been controlled.

When a researcher conducts a survey or engages in naturalistic observation, he can’t control the variables, therefore, he can only establish a correlation between two variables, but not of causality.

A change in a sequence of DNA bases in a bacterial cell has resulted in a mutation. This mutation has increased the ability of the bacteria to break down and digest organic molecules in the environment. Bacteria with this mutation are better able to find and utilize food sources. According to the theory of natural selection, what is MOST likely to occur in future generations of this bacteria? A) The relative frequency of the mutation will increase as time passes. B) Because the mutation has changed the DNA of the bacteria, a new species will be formed. C) Because the mutation is abnormal, the mutation will become more rare with every passing generation. D) Bacteria with the mutation will increase in number until the food supply is exhausted, causing the bacteria to become extinct.

Answer:

The correct answer would be B. CO, which comes from fossil fuel–powered engines, such as cars.

As the name suggests the primary pollutant is defined as the pollutant emitted directly from the source. For example, carbon monoxide which is produced due to incomplete combustion is emitted directly from cars, buses et cetera.

In contrast, secondary pollutant refers to the pollutant which is formed after reacting with other pollutants in the atmosphere. For example, nitrogen dioxide which is formed when NO reacts with oxygen, acid rain which is formed when nitrogen dioxide and sulfur dioxide reacts with water present in atmosphere et cetera.

Answer:

a. While a metaphor is limited in length, an extended metaphor is developed over the course of a poem.

Explanation:

In general, a metaphor is a figure of speech that asserts that one element (person, animal, thing, quality, event, etc.) is similar to another element that in reality, or literally speaking, are not related in any way. While a metaphor is limited in length, an extended metaphor is developed over the course of a poem or throughout a series of sentences in a paragraph

For example, “A dream itself is but a shadow” is a metaphor, its length is limited. And one example of a extended metaphor can be understood with the following poem “Hope is the Thing with Feathers” by Emily Dickinson:

Hope is the thing with feathers

That perches in the soul,

And sings the tune – without words,

And never stops at all,

And the sweetest in the gale is heard;

And sore must be the store

That could abash the little bird

That kept so many warm.

I’ve heard it in the chilliest land,

And on the strangest sea;

Yet, never, in extremity,

It asked a crumb of me.
