(1) should be your answer because Christopher Columbus discovered America in 1492
The correct answer to this question would be alternative D)"Developing countries often specialize in manufacturing and providing raw materials, which can seriously harm the environment."
Alternative D precisely describes the problems for the environment in developing countries.
If you take Brazil, for example, there is plenty of natural resources there, and the soil is fertile for many types of crops, including soy, corn, etc. Animal Husbandry is also a successful activity.
All of these need extensive lands, which can cause deforestation, pollution of the soil, air and of drinkable water. Since these are some of the most important industries of the country, and they're partly responsible for the development of the nation, the government doesn't do much to stop or regulate them, since they need these activities themselves.
A. 45/70
5/7 × 9/10
Multiply the numerator with the other numerator, and denominator with the other denominator.
5 × 9
7 × 10
It becomes 45/70.
B. 23/30
1 3/5 - 5/6
In adding/subtracting fractions, their denominators must be equal. Make them so by finding the LCM of both denominators.
5 and 6 would have an LCM of 30. Make it so the numerator and new denominator still have equal proportion as the first fraction you started with.
1 3/5 becomes 1 3(6) / 5(6), or 1 18/30
5/6 becomes 5(5) / 6(5), or 25/30
You can now subtract both fractions.
1 18/30 - 25/30
The minuend (if the presence of 1 whole is ignored) is smaller than the subtrahend. To fix this, borrow the 1 whole from 1 18/30. 1 in this fraction would be 30, so add 30 to the fraction and remove the 1 in the fraction.
48/30 - 25/30
Subtract.
=23/30.

Our president Donald trump has been targeting undocumented immigrants for example Mexicans that have illegally crossed the U.S Mexican border before under President Barack Obama’s rule undocumented immigrants would be sent back if they had done a crime but wasn’t that small like driving while drinking but now under Donald Trump‘s rule they are sent back if they do anything against the law. Our government has been targeting documented immigrants from Mexico because Donald Trump believes that the US’s lower amount of jobs are because immigrants are taking them.
West Germany prospered economically, while East Germany's growth was stunted.
