Solution

Sentence Analysis

  • Heating oil and natural gas futures rose sharply yesterday, (Main Subject: futures; Main Verb: rose)
  • as long-term forecasts (Dependent clause – Subject: forecasts)
    • for much colder temperatures in key heating regions (prepositional phrase modifying ‘forecasts’)
  • raised fears of insufficient supplies (Verb: raised)
    • capable of meeting the demand this winter. (Modifies ‘supplies’)

The sentence seems to say that X rose sharply yesterday as Y happened.

Y: some forecasts raised fears that supplies would be insufficient to meet the demand this winter.

There is one problem in the sentence:

“insufficient supplies capable of meeting the demand” doesn’t make sense. How are supplies insufficient if they are capable of meeting the demand?

Option Analysis

(A) Incorrect. For the reason mentioned above.

(B) Incorrect. For the following reasons:

  1. “fear of supplies” doesn’t make sense.
  2. “sufficient/insufficient to do X” is preferred over “sufficient/insufficient for doing X”.

(C) Incorrect. This option has redundancy. It is redundant to say that insufficient supplies are unable to meet the demand.

(D) Incorrect. For the following reasons:

  1. “there would be supplies insufficient” is an indirect way of saying the same thing mentioned in option E.
  2. Second error of option B

(E) Correct.
