Doesn't make sense to go for A.
We already know that Winter Wheat yield is going to be lower this year. It is provided in the argument (Because of new government restrictions on the use of Davison River water for irrigation, per acre yields for winter wheat, though not for spring wheat, would be much lower than average.)
The premise tells us that Winter Wheat has a problem when given less water.
Answer C informs us that Sprint Wheat is well adapted to the soil = will have better yield?
Am I stretching it too much and bringing outside assumptions?
Let me try to explain this..
Cost Price of(Expense on) Winter Wheat to farmers(for seeds and all other ) = $100 for 1 kg
Profit Margin = 20%
Sales Price = 1 kg(Output Quantity) *100(CP) * 1.2 =$120
So, before the law on irrigation restrictions, Profit = 120(Revenue) - 100(Expense) = $20
Now, after CP(Cost Price) or Expense of Winter Wheat remains same = $100 for 1 kg
Profit Margin = 20% (Same)
But yield has decreased, for 1 kg sowed, I receive only 0.8 kg yield or Output quantity.
So, the Sales Price for this reduced quantity = 0.8 kg(Output Quantity) * 100(CP) * 1.2 = $96
So, after the law on irrigation restrictions, Profit = 96 (Revenue) - 100 (Expense) = -$4
So it is a net loss. Why? Because the profit margin of 20% is not good enough to cover up the expenses and loss of yield.
Since expenses are considered constant in the question, the question then focuses on loss of yield to blame this loss. This is what A covers up.
If you increase the yield or increase the profit margin, you will get more Profits. That is what A suggests.
If you know what you're worth, then go out and get what you're worth. But you gotta be willing to take the hits, and not pointing fingers saying you ain't where you wanna be because of anybody! Cowards do that and You're better than that!
The path is long, but self-surrender makes it short; the way is difficult, but perfect trust makes it easy.
Fire the final bullet only when you are constantly hitting the Bull's eye, till then KEEP PRACTICING.
Failure establishes only this, that our determination to succeed was not strong enough.
Getting defeated is just a temporary notion, giving it up is what makes it permanent.
Press +1 Kudos, if you think my post gave u a tiny tip.
