Answer: No
Explanation:
the pain and suffering that experimental animals are subject to is not worth any possible benefits to humans. "The American Veterinary Medial Association defines animal pain as an unpleasant sensory and emotional experience perceived as arising from a specific region of the body and associated with actual or potential tissue damage" (Orlans 129). Animals feel pain in many of the same ways that humans do; in fact, their reactions to pain are virtually identical (both humans and animals scream, for example). When animals are used for product toxicity testing or laboratory research, they are subjected to painful and frequently deadly experiments. Two of the most commonly used toxicity tests are the Draize test and the LD50 test, both of which are infamous for the intense pain and suffering they inflect upon experimental animals. In the Draize test the substance or product being tested is placed in the eyes of an animal (generally a rabbit is used for this test); then the animal is monitored for damage to the cornea and other tissues in and near the eye. This test is intensely painful for the animal, and blindness, scarring, and death are generally the end results. The Draize test has been criticized for being unreliable and a needless waste of animal life. The LD50 test is used to test the dosage of a substance that is necessary to cause death in fifty percent of the animal subjects within a certain amount of time. To perform this test, the researchers hook the animals up to tubes that pump huge amounts of the test product into their stomachs until they die. This test is extremely painful to the animals because death can take days or even weeks. According to Orlans, the animals suffer from "vomiting, diarrhea, paralysis, convulsion, and internal bleeding. Since death is the required endpoint, dying animals are not put out of their misery by euthanasia" (154). In his article entitled "Time to Reform Toxic Tests," Michael Balls, a professor of medial cell biology at the University of Nottingham and chairman of the trustees of FRAME (the Fund for the Replacement of Animals in Medical Experiments), states that the LD50 test is "scientifically unjustifiable. The precision it purports to provide is an illusion because of uncontrollable biological variables" (31). The use of the Draize test and the LD50 test to examine product toxicity has decreased over the past few years, but these tests have not been eliminated completely. Thus, because animals are subjected to agonizing pain, suffering and death when they are used in laboratory and cosmetics testing, animal research must be stopped to prevent more waste of animal life.
D. “That he was craving”
A modifier is said to modify (change the meaning of) another element in the structure, on which it is dependent. Typically the modifier can be removed without affecting the grammar of the sentence. So if you remove "That he was craving" from the sentence, it still makes sense and doesn't affect the whole sentence.
