In species such as the red-back spider, the black widow spider, the praying mantis, and the scorpion, the female commonly eats the male after mating. Another widespread form of cannibalism is size-structured cannibalism, in which large individuals consume smaller ones. Octopus, bats, toads, fish, monitor lizards, salamanders, crocodiles, spiders, crustaceans, birds, mammals, and a vast number of insects have all been observed to engage in size-structured cannibalism.  Yet another common form of cannibalism is infanticide. Classical examples include the chimpanzees, where groups of adult males have been observed to attack and consume their infants; and lions, where adult males commonly kill infants when they take over a new harem after replacing the previous dominant males. Also, gerbils and hamsters eat their young if they are stillborn, or if the mothers are especially stressed. Which of the following sentences is the implied main idea?

Although the placebo effect is generally harmless, it does account for the expenditure of millions of dollars on health products and services every year.  Megadoses ofvitamin C have never been proven to treat cancer. Mud baths do not smooth wrinkled skin, nor do electric shocks reduce muscle pain. People who mistakenly use placebos when medical treatment is urgently needed increase their risk for health problems.   The pattern of organization is ______________.
