Answer:
D) the sixteenth amendment allowed congress to break up monopolies
Explanation:
The Sixteenth Amendment to the Constitution of the United States (Amendment XVI) allows the United States Congress to tax an income tax without apportioning it among the states according to their population or based on the results of a census. This amendment excluded Income Tax from the constitutional requirements of direct taxes, after taxes on income, dividends and interest were qualified as direct taxes by the Supreme Court ruling in the Pollock case against Farmers' Loan & Trust Co. (1895). It was ratified in February 1913.
Isaac Newton was creative in his use of prisms to show how white light is actually made up of multiple colors. He used logic in the way he presented his arguments rhetorically in order to convince readers of the correctness of his conclusions.
Newton was not the first to experiment with passing light through prisms to determine how light works. French philosopher Rene Descartes had done prism experiments of his own. But Descartes had thought that passing through a prism actually modified the light in order to produce the color spectrum. Newton correctly understood that when light refracted through the prism, it revealed the range of colors that were naturally in the light. He then used a second prism, blocking all but one color, to show that a single color passing through a prism was not modified in color. He also showed--by positioning the second prism differently--how the multiple colors of light could be recombined into white light again.
Newton's 1672 paper on light refracting through prisms established his reputation as a scientist. He continued to study light throughout his scientific career, publishing a larger work in 1704 on <em>Opticks </em>(as they spelled "optics" then).
