Answer:
- <u>Translated from Portuguese language:</u>
"The gaseous coal is then burned in a gas turbine cycle and part of the residual heat from the exhaust gases is recovered to generate steam for the steam turbine. Currently, the construction of such plants costs about $ 1500 per kW, but their efficiency is about 45%. The average calorific value of coal is about 28,000,000 k J per ton (that is, 28,000,000 k J of heat released when 1 ton of coal is burned). If the mill is to recover its cost difference in five years from fuel savings, determine what the price of coal should be in $ per ton?"
Explanation:
- The price of coal will be around 37 $ per ton. As, a source of energy the coal is more involved in the different industrial and mechanical processes and increases the level of efficiency of different machines by providing a more unique way to obtain greater results.
For this case we have the following dialogue:
Elena: ¿De dónde eres Carlos?
Carlos: Soy de Cuba y mis compañeros son de Estados Unidos. ____________________ son (They are) de Texas.
We note that we must translate the expression in parentheses to fill in the blank.
The expression in parentheses represents the third person of the plural.
For this case, the third person in the plural is male.
Therefore, the correct word is:
"Ellos"
The complete dialogue is:
Elena: ¿De dónde eres Carlos?
Carlos: Soy de Cuba y mis compañeros son de Estados Unidos. Ellos son (They are) de Texas.
Answer:
C. Ellos
