Answer:

The answer is "Halftone".

Explanation:

The technological breakthrough mentioned in the question is the halftone printing method used for the printing of photographs. The technique took advantage of dotting when printing the photos. Instead of using continuous lines, they used dots that differed either in size or tones of black which from a distance, was not observable and looked like a regular photograph but it helped cut down the amount of ink used greatly.

I hope this answer helps.

Which of the following was NOT a goal of Lincoln's Emancipation Proclamation?
Sunny_sXe [5.5K]

Answer, which was NOT a goal of Lincoln's proclamation:  B. to fulfill his lifelong abolitionist ambitions

  • <em>Concerning Lincoln's views on slavery, the History Channel reports, "Lincoln did believe that slavery was morally wrong, but there was one big problem: It was sanctioned by the highest law in the land, the Constitution."  So Lincoln had not been a lifelong abolitionist, due to his respect also for the Constitution.</em>

<u>Historical context/details regarding the Emancipation Proclamation:</u>

President Abraham Lincoln issued The Emancipation Proclamation as an executive order on January 1, 1863. The executive order declared freedom for slaves in  ten Confederate states in rebellion against the Union.  It also allowed that freed slaves could join the Union Army to fight for the cause of reuniting the nation and ending slavery.  As summarized by the Historical Society of Pennsylvania, "The Proclamation broadened the goals of the Union war effort; it made the eradication of slavery into an explicit Union goal, in addition to the reuniting of the country."

While Lincoln personally was strongly against slavery, he had to tread carefully in his role as president and commander-in-chief.  The Emancipation Proclamation was carefully worded in order to retain the support of four border slave states, which remained in the Union though they were states that permitted slavery, were  Maryland, Missouri, Delaware, and Kentucky.   Lincoln wanted to keep those states loyal to the Union cause.

The Emancipation Proclamation was also a way of blocking foreign support for the Confederate cause.  According to the American Battlefield Trust, "Britain and France had considered supporting the Confederacy in order to expand their influence in the Western Hemisphere. However, many Europeans were against slavery."  Britain had abolished slavery in its territories in 1833.  France had put a final end to slavery in its territories in 1848.  So when Lincoln issued the Emancipation Proclamation on January 1, 1863, it also served as a foreign policy action to keep European powers out of the US Civil War, according to Steve Jones, professor of history at Southwestern Adventist University.

Which of congress’s powers is implied through the necessary and proper clause?
Allushta [10]

Answer:

The Necessary and Proper Clause - located in section 8, Article I of U.S. Constitution- relates to the power of Congress to negotiate treaties, as part of the need to create laws that contribute to the enforcement of other powers.

Explanation:

The options for this question are:

A. The power to declare war .

B. The power to restrict child labor.

<em>C. The power to negotiate treaties .</em>

D. The power to print money.

Necessary and Proper Clause gives congress the flexibility to exercise additional powers, considered implied powers, being the negotiation of treaties one of the powers directly related to the clause.

Treaty negotiation involves all international transactions and conventions that are made to achieve mutual benefit, in line with the interests of the nations involved, such as economic and security benefits.

The powers to declare war, restrict child labor and printing money are granted directly to the Congress by the Constitution, and are not related to Necessary and Proper Clause.
