Scientists at the Los Alamos National Laboratory have succeeded for the first time in mining heat
from the Earth's interior and producing energy on a commercial scale, enough for efficient
generation of electricity and heating factories and homes.
(A) and producing energy on a commercial scale, enough for efficient generation of electricity and
heating
(B) and producing enough energy on a commercial scale for electricity to be generated efficiently
and to heat
(C) for energy production on a commercial scale, enough for generating electricity efficiently and to
heat
(D) to produce energy on a commercial scale, enough for generating electricity efficiently and for
heating
(E) to produce enough energy on a commercial scale for efficient generation of electricity and heat
我的疑问是：对于B，第一，producing可不可以看成是与mining并列的？第二，to heat 可不可以看成与to be generated并列，共同修饰electricity？
