Problem:Context: The rotator cuff muscles are important in shoulder movements and in maintaining glenohumeral joint (shoulder joint) stability. These muscles arise from the scapula and connect to the head of the humerus, forming a cuff at the shoulder joint. They hold the head of the humerus in the small and shallow glenoid fossa of the scapula. The glenohumeral joint has been analogously described as a golf ball (head of the humerus) sitting on a golf tee (glenoid fossa).

Question: where is the rotator cuff located on the human body?
Solution:OK... The relevant sentence in the passage is: These muscles arise from the scapula and connect to the head of the humerus, forming a cuff at the shoulder joint.
arise from the scapula and connect to the head of the humerus , forming a cuff at the shoulder joint.

Student A:The Lion, the Witch and the Wardrobe is a fantasy novel for children by C.S. Lewis, published by Geoffrey Bles in 1950. It is the first published and best known of seven novels in The Chronicles of Narnia (1950 -- 1956). Among all the author's books it is also the most widely held in libraries. Although it was written as well as published first in the series, it is volume two in recent editions, which are sequenced by the stories' chronology (the first being The Magician's Nephew). Like the others, it was illustrated by Pauline Baynes, and her work has been retained in many later editions.

Answer this question based on the passage: who wrote the book lion the witch and the wardrobe?
Student B:OK... The relevant information is: The Lion, the Witch and the Wardrobe is a fantasy novel for children by C.S. Lewis, published by Geoffrey Bles in 1950.
C.S. Lewis.

Problem:Chase Center is a multi-purpose arena under construction in the Mission Bay neighborhood of San Francisco. The building will mainly be used for basketball, and is planned to become the new home venue for the National Basketball Association (NBA)'s Golden State Warriors. The Warriors, who have been located in the San Francisco Bay Area since 1962, have played their home games at Oracle Arena in Oakland since 1971. The arena is scheduled to open to the public before the start of the 2019 -- 20 NBA season, with groundbreaking having occurred during the 2016 -- 17 NBA season.

Answer this question: golden state warriors new arena in san francisco?
Solution:OK... The relevant information is: The building will mainly be used for basketball, and is planned to become the new home venue for the National Basketball Association (NBA)'s Golden State Warriors.
Chase Center.

Student A:Staphylococcus epidermidis is a Gram-positive bacterium, and one of over 40 species belonging to the genus Staphylococcus. It is part of the normal human flora, typically the skin flora, and less commonly the mucosal flora. Although S. epidermidis is not usually pathogenic, patients with compromised immune systems are at risk of developing infection. These infections are generally hospital-acquired. S. epidermidis is a particular concern for people with catheters or other surgical implants because it is known to form biofilms that grow on these devices. Being part of the normal skin flora, S. epidermidis is a frequent contaminant of specimens sent to the diagnostic laboratory.

Answer this question based on the passage: where is staphylococcus epidermidis found in the body?
Student B:OK... This is the relevant information: It is part of the normal human flora, typically the skin flora, and less commonly the mucosal flora.
typically the skin flora , and less commonly the mucosal flora.

Student A: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?
Student B:
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 ).
