If you could interview the author of this article, what questions would you ask in order to clarify evidence about the factors that have caused the rise in global temperatures?

how many industries and factories are in 'x' country.

Explanation: the main causes of global temperature rising are factories because, harmful gases can be released. And if the number of the factories increase the percentage of the harmful gas that is being released also increases. So to clarify evidence you can ask :- how many factories does country 'x' have?

By the way 'x' means any one country.

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z

answer

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).
