Read the passage from The Pillow Book.

"Women who have served in the Palace, but who later get married and live at home, are called Madam and receive the most respectful treatment. To be sure, people often consider that these women, who have displayed their faces to all and sundry during their years at Court, are lacking in feminine grace. How proud they must be, nevertheless, when they are styled Assistant Attendants, or summoned to the Palace for occasional duty, or ordered to serve as Imperial envoys during the Kamo Festival! Even those who stay at home lose nothing by having served at Court. In fact they make very good wives. For example, if they are married to a provincial governor and their daughter is chosen to take part in the Gosechi dances, they do not have to disgrace themselves by acting like provincials and asking other people about procedure. They themselves are well versed in the formalities, which is just as it should be.”

What evidence best supports the conclusion that women who serve in the court lead more fulfilling lives than women who do not?

A: “Women who have served in the Palace, but who later get married and live at home, are called Madam.”

B: “These women, who have displayed their faces . . . during their years at Court, are lacking in feminine grace.”

C: “Even those who stay at home lose nothing by having served at Court.”

D:“They themselves are well versed in the formalities, which is just as it should be.”

Answers

what holiday treat was outlawed in europe in the 1700s?

Answers

Answer:

Plumb cake (commonly known as fruit cake)

Hit brainliest if this was helpful :)

Fruit cake are holiday and wedding cakes, both of which contain a lot of fruit. Fruitcake holiday treat was outlawed in Europe in the 1700s.

What do you mean by Treat?

Giving someone a treat involves giving them free food, drink, or amusement.

A ceremonial fruitcake was traditionally cooked in Europe at the conclusion of the nut harvest and kept for consumption the following year to mark the start of the new crop in the hopes of having another successful harvest. Nuts were combined after the harvest to create a fruitcake that was stored for the following year. Fruitcakes from the previous year were eaten at that time in the hopes that their symbolism would bring good harvests again.

Fruitcake, sometimes known as plum cakes, was completely banned throughout Continental Europe at the start of the 18th century. They were referred to as "sinfully rich" cakes. Laws limiting the usage of plum cake were in place by the end of the 18th century.

Therefore, Fruitcake holiday treat was outlawed in Europe in the 1700s.

The main criticism of the Articles of the Confederation is that they
A

B
failed to prevent military rule
c
did not provide enough power for the central government
D
did not provide for a president

Answers

The main criticism that the Articles of Confederation got was that they c did not provide enough power for the central government.

What was the main criticism of the Articles of the Confederation ?

Congress was unable to enforce laws or levy taxes under the Articles of Confederation, which made it impossible for the new country to pay back its obligations from the Revolutionary War.

The federal government was only allowed to ask the states for money, not directly tax the people. Rare state financial contributions prevented the federal government from meeting its obligations or funding programs. International or intrastate trade could not be regulated by the national government.

The central government therefore did not have much power to be a government.
