What was the role of philosophy in medieval thought? What were early philosophers contemplating? How did early Church leaders affect philosophical idea

Answers

Answer:The role of philosophy in medieval thoughts is to propagate religious doctrine especially christian doctrine. It also a means to address or solve theological problems and learnings. Early philosophers contemplates in the field of religion and theology. Also it is times of rediscovery of ancient philosophies that was once lost after the fall of the western roman empire which chaos and destruction ravage due to barbarian invasions. Early church leaders affect the philosophical ideas of this age due to the fact that in this age most educated are from the church. They depose and excommunicate philosophers who opposed their views and philosophy of the world. Also most philosophy of this age is religious oriented and people seek refuge in God for hope and salvation in chaotic times. Early philosophers tend to be more God-oriented and mystical rather than to be logic and rational in thinking.  Also in this age everything are explained through religion and the church doctrine rather than math and science which in the future will play a vital role of Renaissance.

What is the symbolic meaning of the relationship between light and dark in the story in the Araby

Answers

Answer:

Light represents hope, imagination, unrealistic ideas, and the illusion of the narrator, while darkness represents reality, the true nature of things, and despair of the narrator.

Explanation:

The short story "Araby" by James Joyce is a coming-of-age story of a young unnamed narrator who has fantasized a lot about a girl and also about everything that is outside of his reach. This story delves into the theme of imagination vs. reality, where the narrator's wild imagination contrasted greatly with the true nature of the real world.

Symbolism is one style that Joyce used in his short story. He presents the image of light and dark to signify two very different things, as is evident. He uses light to show the illusion, unrealistic ideas, and hope that the narrator has for the much older girl. Darkness, in return, represents the failure, the despair, the reality, and the true nature of the narrator's predicament.  

Exact Answer:

Light and dark imagery pervade this story. At the beginning, we learn that the narrator's street has "dark muddy lanes" and "dark dripping gardens." His own street is "blind," as if it were also in the dark, even though “blind” also means that the street is a dead-end. These elements of darkness suggest the narrator's lack of awareness, as well as the blindness that exists in his own community.

Light is associated with Mangan's sister, the narrator's love interest, whom he knows mostly through observing her from his house and whose beauty intrigues him. He sees her figure by way of "the light from the half-opened door." The bazaar is also associated with light when the narrator is looking forward to it. Later, though, because he arrives at the bazaar late, he finds the hall with closed stalls and "in darkness."

Joyce uses light and dark to develop the theme of harboring false hopes and having them exposed. The narrator builds the expectation that Mangan’s sister and the trip to the bazaar will lift him from his drab existence. When he arrives at the bazaar, his dreams are shattered by the shabbiness of the place. The darkening hall symbolizes the narrator’s realization that his dream was an illusion.

Answers

Answer: Strike while the iron is hot. If you wait, you miss the opportunity to make a difference. If the issue is burning, it has people's attention. Speak up and be heard when they are likely to respond.

Explanation: The expression comes from blacksmithing. The blacksmith heats a bar of iron in the forge until it is red hot. Then the smith places the iron on the anvil and strikes it with a mallet to shape it. The red hot metal is soft enough to bend or flatten, Once the iron is cold, it is very difficult to bend or shape. The smith must reheat it if there is more work to be done.

Answers

Answer: c. Managing his liquidity

Explanation:

Barry will be getting less money than he is used to and so will need to manage his lifestyle in a way that he can maintain himself with this reduced cashflow.

The way to do this is to manage his liquidity. Liquidity refers to the flow of cash and so managing it refers to adopting strategies and methods that will enable a person use the money they have in such a way that it meets their obligations with the amount that they have.

Explanation:

Throughout the novel, there are references to light and darkness, which take on different meanings if they are understood either literally or figuratively. What does the light figuratively symbolize? What does the darkness figuratively symbolize? (Hint: think back to Plato's "The Allegory of the Cave.")

Answers

Answer:

The darkness figuratively symbolizes ignorance

Explanation:

From the book, The Allegory of the Cave, the author used certain allegories to show the meaning of certain things.

Plato wrote The Allegory of the Cave to describe certain people who have lived their lives chained to a wall of a cave while staring at a blank wall.

It is described that it was likened to a philosopher who was freed from a cave and finds out that the shadows on the wall are imaginary.

Darkness from the book signifies ignorance.

Which of these phrases matches the style of Bradford’s writing a Meal of brown bread and boiled cabbage a Cacaphony jarring jangling discordance as bright as a glittering multifaceted jewel in a golden crown running like cheetahs

Answers

Answer:

A). A Meal of brown bread and boiled cabbage.

Explanation:

William Bradford's writing style is characterized by simplicity, clarity, and straightforwardness so that the intended meaning or message is conveniently understood by the readers without any strings or complications. In his 'Plymouth Plantation', he has employed a very plain, clear imagery, and straightforward writing style to display the aesthetic virtues associated with a simplistic writing style. Thus, the phrase that reflects Bradford's writing style would be 'a meal of brown bread and boiled cabbage' as it states the idea in a plain, clear, and straightforward manner. Hence, it justifies the above claim and therefore, option A is the correct answer.

The paragraph contains several sentence fragments. Decide if the selection in bold needs to be revised or if it is correct as is.
Near the Normandy coast of northern France, the village of Bayeux houses a remarkable treasure. The Bayeux Tapestry may be found in its
own museum in the former Great Seminary of Bayeux. Also known as the Tapestry of Queen Matilda or the Cloth of the Conquest. This tapestry
is unusual. Because it is a very long, narrow strip of linen measuring 70 meters by 50 centimeters. The tapestry is actually an embroidery of
William the Conqueror's invasion and conquest of England in 1066. It consists of fifty-one scenes and depicts more than 1,500 figures.
Including warriors, horses, other animals, ships, castles, weapons, and other objects. Latin words are embroidered on the scenes. To explain
what is taking place at each stage of the invasion and battle.
Which option below would be an acceptable revision of the selection in bold?
a. No revision is necessary.
b. It consisted of fifty-one scenes and depicting more than 1,500 figures.
Oc Consisting of fifty-one scenes and depicting more than 1,500 figures.
d. Therefore, it consists of fifty-one scenes and depicting more than 1,500 figures.

Answers

Answer:

I think, and from my point of view D is acceptable

Among all the given options, the one which is an acceptable revision of the selection in bold is “Therefore, it consists of fifty-one scenes depicting more than 1,500 figures.” Hence, Option D is correct.

What is revision?

Revision is a process that can be done in written as well as verbal form. When a revision is done in writing, in this form basically paragraphs, sentences, or words are rearranged, added, or removed.

While doing the revision, writers do work on the write-ups after the work of drafting is completed. All the thing that is done by them adding or rearrangement of paragraphs, sentences, or words is done.

Some of the illustrations of revision are a book editor removing unnecessary content from a book, an editor has removed content from the article, and many more.

Thus, Option D is correct.

The Spanish version is more effective.

Explanation:

Even though both versions are beautiful, in the translated one some figures of speech are lost, for example, in "venid a ver" there is an ALLITERATION that has a sound effect (the repetition of letter v) in the original language that is not shown in the English version.  

Besides, "venid a ver" would be more effective if translated as  'come to see' (literal translation) instead of 'come and see'.
