Question: People from two villages ate lots of salt. People from Salt village used regular salt, while people from Sand village people used iodized salt in their diets, after talking to specialists.  Given the paragraph above, please answer correctly the following question:   Which village had fewer people experience developmental difficulties?  Hint: Before iodized salt was developed, some people experienced a number of developmental difficulties, including problems with thyroid gland function and mental retardation. In the 1920s, we learned that these conditions could usually be treated easily with the addition of iodide anion to the diet. One easy way to increase iodide intake was to add the anion to table salt. This simple step greatly enhanced health and development. Large amounts of iodide ion are also found in seaweed such as kelp (see picture above) and saltwater fish.
Answer: Sand

Question: Two counties were part of the same region. Green county used alternative methods to produce energy, while Brown county used fossil fuels and released a lot of carbon dioxide into the atmosphere.  Given the paragraph above, please answer correctly the following question:   Which county released fewer greenhouse gases in Earth's atmosphere?  Hint: Carbon dioxide is the most significant long-lived greenhouse gas in Earth's atmosphere. Since the Industrial Revolution anthropogenic emissions – primarily from use of fossil fuels and deforestation – have rapidly increased its concentration in the atmosphere, leading to global warming.  Carbon dioxide also causes ocean acidification because it dissolves in water to form carbonic acid.
Answer: Green

Question: All marine creatures are not fish. There are some mammals, for example, whales, also live in the water. Rob wants to know more about differences between fish and other non fish creatures in the water. He divided them into two groups, group A and group B. Group A consists of fish, and group B consists of non fish creatures in the water. He started to see the differences between these two groups.  Given the paragraph above, please answer correctly the following question:   In group A, would the eggs most likely develop outside or inside the mother's body?  Hint: Fish reproduce sexually. They lay eggs that can be fertilized either inside or outside of the body. In most fish, the eggs develop outside of the mother's body. In the majority of these species, fertilization also takes place outside the mother's body. The male and female fish release their gametes into the surrounding water, where fertilization occurs. Female fish release very high numbers of eggs to increase the chances of fertilization.
Answer:
outside
