When the sun and moon are near the horizon, we notice that they are distorted from a circular form into ovals, and are usually of a reddish colour. the former effect is due to the fact that the amount of refraction changes rapidly near the horizon, being greater below than above. thus the lower edges of these bodies are raised more than the upper ones, so that the vertical diameter is diminished. the horizontal diameter is not affected, and so the sun and moon appear to be oval and not circular. their reddish colour is due to absorption. white light is composed of all the “colours of the rainbow” —red, yellow, green, blue, violet, etc., —and of these, the green, blue, and violet (the shorter “waves”) are more readily absorbed by the atmosphere, or rather its vapours (for pure dry air exercises scarcely any absorption), than the red and yellowish rays (which are longer). thus this process of selective absorption results in the loss of a greater amount of the blue and violet rays, and so the sun and moon, when seen low down near the horizon, appear reddish or yellowish rather than white, an effect seen also when the sun shines through a “november fog.” the sentence (or section) in all caps is an example of the main idea. true false

Will anyone be able to check for grammatical errors and give an opinion on the essay itself? write about the following topic: some people believe that allowing children to make their own cholces on everyday matters (such as food, clothes and entertainment) is likely to result in a society of individuals who only think about their own wishes. other people believe that it is important for children to make decisions about matters that affect them. discuss both these views and give your own opinion. —— nowadays, in this busy and fast developing world teaching children from an early age to cope with their own decisions (such as food, clothes etc.) and then take the coincidences after that is something that a lot of people believe that it is important for them. on the other hand other people think that it might end up in a society of humans who put their wishes before anyone else's. but which one of these views will predominate? firstly, the people who allow their children to make their own decisions are the people who everyone should look up to. it is important to let your children learn from the mistakes their make. the parents can not be with them all the time every day and for that reason, teaching them to deal with their decisons or even problems will them in the future. of course, there are always disadvantages such as some people may really forget about that their children will need them at a certain point in life and may loose connection whit them. but that is why it should have that moderately path, where kids will make their own decisions but will feel comfortable to always ask for a advice tueur parents. on the other hand, there are and the second type of parents which think that too much individualism is not good. it really depends on the parents how they will teach their children to carry on with the independence they have. a lot of them might forget that they are still kids and will need and advices from time to time and because of that the parents turn their kids in individuals who only think about their own wishes due to the fact that they are let on their own and have to cope with everyone and everything by themselves. in conclusion, i think that the best decision someone can make is to look up to the first type of parents. that way they will be able to train their children to become independent people who will respect the wishes of others and they will be able to cope with their decisions in the future when they need it.
