    Men who exercise often are less likely to die from cancer than those who【C1】______, new research published in the British Journal of Cancer revealed yesterday.
    A team of scientists from the Karolinska Institute in Sweden looked【C2】______the effect of physical activity and cancer risk in 40, 708 men【C3】______between 45 and 79.
