United States manufacturers currently produce most of the world's solar-power generators--most of which are exported to Europe. However, European manufacturers are emerging and probably will ultimately capture much of the European market.

If these initiatives succeed in increasing the demand for solar-power generators in the United States, United States manufacturers will probably maintain significant production levels, since __________. (A) some United States manufacturers have been substantially increasing their output over the last several years (B) the efficiency of solar-power generators in converting energy from the Sun into electric power is not improving as fast as it once did (C) just as European manufacturers enjoy certain competitive advantages in Europe, so do United States manufacturers in the United States (D) European governments are currently undertaking initiatives to stimulate the use of solar power within Europe (E) the current market for solar-power generators in the United States is very limited 這題的答案是C 雖然最後答案憑直覺選對了可是後來仔細回來看我還是看不動這題的思路是什麼~ 另外想請問~PPCR有人有詳解嗎(詳解指的是包括解釋說明的) 謝謝~~~ -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 218.164.128.23
