35. Because of increases in the price of oil and because of government policies promoting energy conservation, the use of oil to heat homes fell by 40 percent from 1970 to the present, and many homeowners switched to natural gas for heating. Because switching to natural gas involved investing in equipment, a significant switch back to oil in the near future is unlikely.

The prediction that ends the passage would be most seriously called into question if it were true that in the last few years.

A. the price of natural gas to heat homes has remained constant, while the cost of equipment to heat homes with natural gas has fallen sharply.
B. the price of home heating oil has remained constant, while the cost of equipment to heat home with natural gas has risen sharply.
C. the cost of equipment to heat homes with natural gas has fallen sharply, while the price of home heating oil has fallen to 1970 levels.
D. the cost of equipment to heat homes with oil has fallen sharply, while the price of heating with oil has fallen below the price of heating with natural gas
E. the use of oil to heat homes has continued to decline, while the price of heating oil has fallen to 1970 levels

I choose B but the answer is D.
I can't figure it out even though it looks simple.

一些個人淺見...獻醜了...請各位大哥指教...

首先題目要的是weaken最後一句話...
也就是說雖然switch back to oil要花錢...但是人們還是會換回heat with oil...

d明確說明換回oil的設備成本下降...並且oil使用成本也比gas的低
明確削弱了文章最後一句話...所以選d

至於b說oil使用成本不變,gas使用成本上漲,並沒有d來的好因為他沒考慮到switch back的設備成本...如果說gas使用成本上升幅度仍小於換回oil的設備成本...那大家還是會用gas...因此沒weaken (H)
