QUES: In many people, the infection waxes and wanes. Tissue destruction and necrosis are often balanced by healing and fibrosis. Affected tissue is replaced by scarring and cavities filled with caseous necrotic material. During active disease, some of these cavities are joined to the air passages bronchi and this material can be coughed up. It contains living bacteria, so can spread the infection. Treatment with appropriate antibiotics kills bacteria and allows healing to take place. Upon cure, affected areas are eventually replaced by scar tissue.
What medicine treats scar tissue?

QUES: During the 1950s the rivalry was exacerbated further when there was a controversy surrounding the transfer of Alfredo di Stéfano, who finally played for Real Madrid and was key to their subsequent success. The 1960s saw the rivalry reach the European stage when they met twice in a controversial knock-out round of the European Cup, with Madrid receiving unfavourable treatment from the referee. In 2002, the European encounter between the clubs was dubbed the "Match of The Century" by Spanish media, and Madrid's win was watched by more than 500 million people.
How many people watched the Match of the Century?

ANS: 500 million

QUES: The hole walls for boards with two or more layers can be made conductive and then electroplated with copper to form plated-through holes.  These holes electrically connect the conducting layers of the PCB. For multi-layer boards, those with three layers or more, drilling typically produces a smear of the high temperature decomposition products of bonding agent in the laminate system. Before the holes can be plated through, this smear must be removed by a chemical de-smear process, or by plasma-etch. The de-smear process ensures that a good connection is made to the copper layers when the hole is plated through. On high reliability boards a process called etch-back is performed chemically with a potassium permanganate based etchant or plasma. The etch-back removes resin and the glass fibers so that the copper layers extend into the hole and as the hole is plated become integral with the deposited copper.
What connects the conducting layers of the PAB?

ANS: unanswerable

QUES: A person's self-report is the most reliable measure of pain, with health care professionals tending to underestimate severity. A definition of pain widely employed in nursing, emphasizing its subjective nature and the importance of believing patient reports, was introduced by Margo McCaffery in 1968: "Pain is whatever the experiencing person says it is, existing whenever he says it does". To assess intensity, the patient may be asked to locate their pain on a scale of 0 to 10, with 0 being no pain at all, and 10 the worst pain they have ever felt. Quality can be established by having the patient complete the McGill Pain Questionnaire indicating which words best describe their pain.
What scale might a patient be asked to locate their pain on?

ANS:
0 to 10
