TASK DEFINITION: Given a text passage, come up with an appropriate title for it. The title should accurately represent what the main focus of the passage is. The title of a passage may be present in the first few sentences of the passage and/or be referred to multiple times in the passage. The title should be 1-5 words long.
PROBLEM: Valley Forge functioned as the third of eight military encampments for the Continental Army 's main body , commanded by General George Washington . In September 1777 , British forces had captured the American capital of Philadelphia . After failing to retake the city , Washington led his 12,000 - person army into winter quarters at Valley Forge , located approximately 18 miles ( 29 km ) northwest of Philadelphia . They remained there for six months , from December 19 , 1777 to June 19 , 1778 . At Valley Forge , the Continentals struggled to manage a disastrous supply crisis while retraining and reorganizing their units . About 1,700 to 2,000 soldiers died due to disease , possibly exacerbated by malnutrition .

SOLUTION: Valley Forge

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 .

SOLUTION: X-ray filter

PROBLEM: 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 .

SOLUTION:
Staphylococcus epidermidis
