It means that people will know if they are suffering from an illness, meaning that they have the advantage of being able to treat it. A disadvantage could be that if a disease is inactive or uncurable the person would be put through stress for no reason.
Nigeria is very hot, if you see pictures of Nigeria you can see how the sun is shining very brightly on the houses and on people. Their color of their skin are adapted to support the sun hot temperature.
I'm not exactly sure what you are trying to ask..
However, here is my take on your problem.
36 = Total before the day
8 = Total at the end of the day
36 - 8 = 28 <em>This is how many packages were left.
</em>36 = 28 + 8 <u /><em>This is a possible equation, it contains two terms (28, 8).
</em>36-8=28 <em>This is another possible equation that is equvilent to the previous suggested one.</em><em>
</em>Hope this helps!<em>
