Problem:Passage: The Emancipation Statue is a public sculpture symbolising the "breaking of the chains" of slavery at Emancipation. It is located in Barbados, east of Bridgetown at centre of the J.T.C. Ramsay roundabout formed at the junction of the ABC Highway and Highway 5. Many Barbadians refer to the statue as Bussa, the name of a slave who helped inspire a revolt against slavery in Barbados in 1816, though the statue is not actually sculpted to be Bussa.

Question: Based on this passage, where is the statue of bussa in barbados?
Solution:OK... This is the relevant information: It is located in Barbados, east of Bridgetown at centre of the J.T.C. Ramsay roundabout formed at the junction of the ABC Highway and Highway 5.
east of Bridgetown at centre of the J.T.C. Ramsay roundabout formed at the junction of the ABC Highway and Highway 5.

Student A:Passage: Human fertilization is the union of a human egg and sperm, usually occurring in the ampulla of the fallopian tube. The result of this union is the production of a zygote cell, or fertilized egg, initiating prenatal development. Scientists discovered the dynamics of human fertilization in the nineteenth century.

Question: Based on this passage, a cell that is formed from the union of the sperm and ovum is called?
Student B:OK... To answer the above question, the relevant sentence is: The result of this union is the production of a zygote cell, or fertilized egg, initiating prenatal development.
a zygote cell , or fertilized egg.

Problem:The Convention approved the Committee's Electoral College proposal, with minor modifications, on September 6, 1787. Delegates from states with smaller populations or limited land area such as Connecticut, New Jersey, and Maryland generally favored the Electoral College with some consideration for states. At the compromise providing for a runoff among the top five candidates, the small states supposed that the House of Representatives with each state delegation casting one vote would decide most elections.

Answer this question: when did we start using the electoral college?
Solution:OK... The relevant information is: The Convention approved the Committee's Electoral College proposal, with minor modifications, on September 6, 1787.
September 6 , 1787.

Problem:For medical purposes, X-ray filters are used to selectively attenuate, or block out, low-energy rays during x-ray imaging (radiography). Low energy x-rays (less than 30 keV) contribute little to the resultant image as they are heavily absorbed by the patient's soft tissues (particularly the skin). Additionally, this absorption adds to the risk of stochastic (e.g. cancer) or non stochastic radiation effects (e.g. tissue reactions) in the patient. Thus, it is favorable to remove these low energy X-rays from the incident light beam. X-ray filtration may be inherent due to the X-ray tube and housing material itself or added from additional sheets of filter material. The minimum filtration used is usually 2.5 mm aluminium (Al) equivalent, although there is an increasing trend to use greater filtration. Manufacturers of modern fluoroscopy equipment utilize a system of adding a variable thickness of copper (Cu) filtration according to patient thickness. This typically ranges from 0.1 to 0.9 mm Cu.

Based on this passage, the function of an x ray beam filter in diagnostic radiology is to?
Solution:
OK... To answer the question, consider the following: For medical purposes, X-ray filters are used to selectively attenuate, or block out, low-energy rays during x-ray imaging (radiography).
selectively attenuate , or block out , low - energy rays during x-ray imaging ( radiography ).
