The correct answer is A.

<u>The dependent variable is:</u><u> how long students worked on the math problem.</u> Secondly, the goal of the study is to assess whether an explanatory variable (the confort of chairs) does have a causal effect on the lenght of math study or not.  

As it is described in the question, the explanatory variable is a binary one: it takes value equal to 1 for the group seated in padded, comfortable chairs, and value 0 for the individuals in the group with standard chairs. Therefore, the study can be understood as the assesment on the validity of a treatment, on its capacity to make a difference on the dependent variable.

What was the impact of the Amritsar Massacre?
Elena-2011 [213]

Answer:

A

Many Indians joined the British military to fight in World War I.

Explanation:

The Amritsar massacre fundamentally changed how the Indians saw the Raj (the era of British rule, which ran from 1757 to 1947). It led Mahatma Gandhi, who during the first world war had forsaken his pacifism to help recruit soldiers to preserve the empire, to see British rule as satanic.

Harman [31]
Akhenaten (pronounced /ˌækəˈnɑːtən/),[8] also spelled Echnaton,[9] Akhenaton,[3] Ikhnaton,[2] and Khuenaten[10][11] (Ancient Egyptian: ꜣḫ-n-jtn, meaning "Effective for the Aten"), was an ancient Egyptian pharaoh reigning c. 1353–1336[3] or 1351–1334 BC,[4] the tenth ruler of the Eighteenth Dynasty. Before the fifth year of his reign, he was known as Amenhotep IV (Ancient Egyptian: jmn-ḥtp, meaning "Amun is satisfied", Hellenized as Amenophis IV).

Atenism
Akhenaten is noted for abandoning Egypt's traditional polytheistic religion and introducing Atenism, worship centered on Aten. The views of Egyptologists differ whether Atenism should be considered as absolute monotheism, or whether it was monolatry, syncretism, or henotheism.[12][13] This culture shift away from traditional religion was not widely accepted. After his death, Akhenaten's monuments were dismantled and hidden, his statues were destroyed, and his name excluded from lists of rulers compiled by later pharaohs.[14] Traditional religious practice was gradually restored, notably under his close successor Tutankhamun, who changed his name from Tutankhaten early in his reign.[15] When some dozen years later rulers without clear rights of succession from the Eighteenth Dynasty founded a new dynasty, they discredited Akhenaten and his immediate successors, referring to Akhenaten himself as "the enemy" or "that criminal" in archival records.[16][17]

Akhenaten was all but lost to history until the late 19th century discovery of Amarna, or Akhetaten, the new capital city he built for the worship of Aten.[18] Furthermore, in 1907, a mummy that could be Akhenaten's was unearthed from the tomb KV55 in the Valley of the Kings by Edward R. Ayrton. Genetic testing has determined that the man buried in KV55 was Tutankhamun's father,[19] but its identification as Akhenaten has since been questioned.[6][7][20][21][22]

Akhenaten's rediscovery and Flinders Petrie's early excavations at Amarna sparked great public interest in the pharaoh and his queen Nefertiti. He has been described as "enigmatic", "mysterious", "revolutionary", "the greatest idealist of the world", and "the first individual in history", but also as a "heretic", "fanatic", "possibly insane", and "mad".[12][23][24][25][26] The interest comes from his connection with Tutankhamun, the unique style and high quality of the pictorial arts he patronized, and ongoing interest in the religion he attempted to establish.
