ROME (Reuters) - Mario Monti formed a new technocrat government in Italy on Wednesday to tackle a major debt crisis threatening the entire euro zone and said he hoped it would placate financial markets. President Giorgio Napolitano swore in a 16-member government, including three women, at his palace on Wednesday afternoon, ending a chaotic political crisis that has placed Italy at the center of the euro zone's burgeoning problems. The government now has the urgent task of tackling a broader crisis that has pushed Italy's borrowing costs to untenable levels and brought it to the brink of economic disaster. Monti said: "We feel sure of what we have done and we have received many signals of encouragement.
