Why do you think a poet might write a lyric poem?

Answers

Answer:

yeah

Explanation:

Similar approaches to poetry were developed in other parts of the world. Between the fourth century B.C. and the first century A.D., Hebrew poets composed intimate and lyrical psalms, which were sung in ancient Jewish worship services and compiled in the Hebrew Bible. During the eighth century, Japanese poets expressed their ideas and emotions through haiku and other forms. Writing about his private life, Taoist writer Li Po (710–762) became one of China's most celebrated poets.

The rise of lyric poetry in the Western world represented a shift from epic narratives about heroes and gods. The personal tone of lyric poetry gave it broad appeal. Poets in Europe drew inspiration from ancient Greece but also borrowed ideas from the Middle East, Egypt, and Asia.

Types of Lyric Poetry

Of the three main categories of poetry—narrative, dramatic, and lyric—lyric is the most common, and also the most difficult to classify. Narrative poems tell stories. Dramatic poetry is a play written in verse. Lyric poetry, however, encompasses a wide range of forms and approaches.

b. The Ottomans and French cooperated to colonize North Africa
c. The Ottomans supported nationalism in the Balkans to destabilize Europe
d. The Ottomans alliance with the Russians, English and French sought to impede German unification

Answers

Answer:

a. Russian, English, and French expansion came at the expense of the Ottomans

Explanation:

Between the years 1815 to 1914, the Ottoman Empire experienced a decline in its powers and influence.

The decline was caused majorly by series of alliances and conflicts with the European powers at the time such as the British, French, and Russia.

For example, the Crimean War lasted between 1853 to 1856.

Also, the effects of the Russo-Turkish war between 1877 to 1878

All of these were a result of the European power expansion agenda which led to the dividing and eventual dissolution of the Ottoman Empire.

B. Local property taxes on those homes would drop to keep demand high.
C. Construction of those homes would not decrease because supply is inelastic.
D. more resources would be allocated to the building of 2,400-square-foot homes.

Answers

Answer:

The correct answer is D. If the government levied a luxury tax on homes with more than 2,500 square feet of space, more resources would be allocated to the building of 2,400-square-foot homes.

Explanation:

If the government were to increase taxes on buildings over 2,500 square feet, the demand for these buildings would most likely drop drastically, since this tax would mean a higher monthly maintenance cost for homeowners.

Therefore, this drop in demand would also cause supply to decline, since it would be uneconomical for builders to carry out projects of this type. Therefore, most of the supply would be allocated around buildings of less than 2,400 square feet of surface.

What was a major reason the North defeated the South in the Civil War? (SSUSH9a)

A
North was more industrialized and had better use of railroads/telegraph
B
South actually won the war because of its ability to fight and superior infrastructure
C
North features better generals and soldiers by lacked industrialization
D
South actually had more people for the war, but lacked disciplined generals

Answers

Answer:

A.

Explanation:

The American Civil War was won by the Union. When Confederate General Robert E. Lee surrendered his forces to Union General Ulysses S. Grant at Appomattox Court House in Virginia in April 1865, the war was formally over. On June 2, Galveston, Texas, witnessed the last Confederate troop surrender on the western frontier.

Explain about the major reason the North defeated the South in the civil war?

The more industrialized North of the USA generated 97% of its weapons and pig iron. The North was wealthier and more diverse than the South, even in terms of agriculture. The Union's superior navy precluded the Confederacy from doing business with Europe.

The institution that led to secession—slavery—was the most persuasive "internal" cause in the South's defeat. Slaves escaped and joined the Union army, starving the South of labor and adding more than 100,000 men to the North.

The American Civil War was effectively over when Confederate leader Robert E. Lee's Army of Northern Virginia submitted on April 9, 1865, at Appomattox Court House (1861–1865).

The answer is A

In what two ways were candidates chosen and 1816

Answers

by legislatures not the most popular vote

In 1816, candidates for political office were chosen in two main ways:

CaucusNomination by State Legislatures

What are a caucus and conference?

Members of the United States Congress from each major party meet regularly in closed sessions known as party meetings (Republicans) or party caucuses (Progressives) (Democrats). The participants set the agenda, select committee members instead chairs, and hold elections to determine which floor leaders will be elected.

Political caucuses were meetings held by political parties to select their candidates for public office. During the caucus, party members would discuss and debate the merits of various candidates, and then vote to select a nominee. In some cases, the caucus would be open to all party members, while in others it would be limited to a smaller group of party leaders.

In many states, candidates for public office were nominated by the state legislature, rather than by a political caucus. State legislators would discuss and debate the merits of various candidates, and then vote to select a nominee. This process was particularly common for state-level offices, such as the governor and state legislature, but was also used for national-level offices, such as the U.S. Senate.

In The Mystery of the Lost Gem, Sherlock used his sight to find that the "furniture, books, pens, and pencils were all in their proper places." The thief didn't look around for valuables. This observation was the first clue that the thief lived or worked at the house. The fact that the safe that was not damaged also supported this theory. The locked windows and door confirmed the observation as well. Next, Sherlock listened to Mrs. Blakely's recount of events in the hallway. He used her information to search for more clues.
