Teacher: Write a phrase, the answer to which is present in the passage. The answer to this question should be completely and unambiguously found in the passage. The query must be about a single or multiple linked entities.
Teacher: Now, understand the problem? If you are still confused, see the following example:
Most people should get all the nutrients they need by having a varied and balanced diet, although some few people may need to take extra supplements. What this guide covers This guide has information about: Bonus: Like potassium, calcium helps regulate blood pressure. On your plate: milk (and other dairy products), spinach, beans and calcium-fortified products. 4. Magnesium: One of the most underrated minerals, magnesium is involved in over 300 chemical reactions in your body. other vitamins and minerals including beta-carotene, copper, potassium and zinc ; Use these links to find out what these nutrients do, how much of them you need, how to ensure you get enough, and what the risks are if you take too much.

According to Nobel Prize-winner Dr. Linus Pauling, you can trace every health ailment to a mineral deficiency. Who knew?Stress, for example, robs your body of magnesium. An iron deficiency can make you feel lethargic -- and compromise your immunity. On your plate: bananas, baked potatoes, raisins, tomatoes and artichokes. 1 3. Calcium: Sure, calcium helps build strong bones, but it also helps prevent PMS (a welcome side effect for women everywhere). 2 4. Magnesium: One of the most underrated minerals, magnesium is involved in over 300 chemical reactions in your body. other vitamins and minerals including beta-carotene, copper, potassium and zinc Use these links to find out what these nutrients do, how much of them you need, how to ensure you get enough, and what the risks are if you take too much. Vitamins and minerals are nutrients your body needs in small amounts to work properly and stay healthy. Most people should get all the nutrients they need by having a varied and balanced diet, although some few people may need to take extra supplements. What this guide covers. This guide has information about: vitamin A B vitamins and folic acid So which minerals do you need, and how do you add them to your diet? Minerals are incredibly important for health and to prevent chronic disease. Without them we'd suffer from osteoporosis, PMS, high blood pressure and low energy, just to name a few, says Karen Ansel, a registered dietitian in New York.
Solution: the importance of minerals in diet
Reason: The passage is about the importance of nutrients in a diet. This includes minerals, and hence, the question of importance of minerals can be answered from the information in the passage.

Furthermore, the irradiation effect can occur as a long-term reaction due to the presence of free radicals [27, 28]. The effects of irradiation on the degradation of PLA after exposure and during shelf life of PLA have not been much studied. Blanco and Siracusa examined the effect of various coatings on thermal degradation of PLA, but did not examine irradiation or biodegradation. See how the DuPont approach to solving global challenges is rooted in science and driven by extraordinary material, chemical, biological and engineering capabilities. The effect of neutron irradiation on the deformation behavior at various strain rates in zirconium and its alloys is not well understood. Plastic instability phenomena in neutron irradiated zircaloy is related to inhomogene ous deformation, characterized by concentra--41 In the present study, room-temperature Irradiation has become an important commercial sterilization method for foods and pharmaceuticals; however, it can cause changes in the chemical structure of polymeric materials such as crosslinking and/or chain scission [24, 25, 26]. Furthermore, the irradiation effect can occur as a long-term reaction due to the presence of free radicals [27, 28]. The effects of irradiation on the degradation of PLA after exposure and during shelf life of PLA have not been much studied. Blanco and Siracusa [29] examined the effect of various coatings on thermal degradation of PLA, but did not examine irradiation or biodegradation. are around 50 C. Most plastic materials are compatible with EtO sterilization. 2.3. - Radiation Radiation is a type of "cold" sterilization. Gamma Sterilization Sterilization by gamma radiation uses the radioisotope Cobalt 60 as its energy source. Once formed, Cobalt 60 instantly begins to decay, releasing energy in the form of gamma rays. The film samples were irradiated at a target-absorbed dose of 30 kGy. Gamma irradiated samples (GM) were treated at a dose rate of 3200 s/kGy. For E-beam irradiation (EB), accelerated beam currents of 1.5 and 15 mA were used. Both irradiation processes were carried out in the presence of air at room temperature. The effect of neutron irradiation on the tensile deformation behavior of zirconium was examined at room temperature at various strain rates ranging of 2.2 x 10--2.2 x 10- sec-'. The microstructure of the deformed specimens was observed by transmission electron microscopy. It was established that neutron irradiation diminishes the uniform elongation and the strain hardening rate, and hastens the onset of plastic instability. These phenomena are attributed to inhomogeneous deformation in the dislocation chan nels in the irradiated and deformed zirconium. The main disadvantage associated with gamma irradiation concerns the potentially damaging effects of gamma rays on the product, particularly those products that contain polymeric components. Another drawback with this technique is the bulky shielding required to store the radioisotope .
