Snowing had begun several days earlier, with snow reaching a peak thickness of 70 cm (28 inches) in Troodos. Four hundred customers lost electricity, and several villages, including Armenohori, Farmakas, Kampi, and Sina Oros, completely lost it for extended periods of time.

It was shot entirely at Pinewood Studios, with scenery created with miniatures and computer graphics. Rossum, Wilson and Driver had singing experience, but Butler had none and so had music lessons. The Phantom of the Opera grossed $154.6 million worldwide and received mixed to negative reviews from critics, but was very well received by audiences. Critics praised the visuals and acting (particularly Rossum's performance) but criticized the writing and directing.

It differs from a parliamentary republic in that it has a popularly elected head of state, who is more than a purely ceremonial figurehead, and from the presidential system in that the cabinet, although named by the president, is responsible to the legislature, which may force the cabinet to resign through a motion of no confidence.
 Question: can a country have both a president and a prime minister Context: As the century progressed, some surgical interventions, including the pneumothorax or plombage technique--collapsing an infected lung to ``rest'' it and allow the lesions to heal--were used to treat tuberculosis. Pneumothorax was not a new technique by any means. In 1696, Giorgio Baglivi reported a general improvement in tuberculosis sufferers after they received sword wounds to the chest. F.H. Ramadge induced the first successful therapeutic pneumothorax in 1834, and reported subsequently the patient was cured. It was in the 20th century, however, that scientists sought to rigorously investigate the effectiveness of such procedures. In 1939, the British Journal of Tuberculosis published a study by Oli Hjaltested and Kjeld Törning on 191 patients undergoing the procedure between 1925 and 1931; in 1951, Roger Mitchell published several articles on the therapeutic outcomes of 557 patients treated between 1930 and 1939 at Trudeau Sanatorium in Saranac Lake. The search for a medicinal cure, however, continued in earnest.
