Answers: 1. When things go wrong, Carl tends to brood for hours and to blame others. 3. The school was closed not only because of the snow and ice but also because of the lack of heat. 4. The ice was a greater problem for the electrical power company than for the natural gas company.
Step-by-step explanation:
Parallel structures in sentences consist of the repetition of a grammatical pattern. This makes sentences have grammatical consistency and flow naturally. Below, I analyze each of the sentences:
1. When things go wrong... This sentence shows parallelism because the elements "to blame others" and "to brood for hours" have the same grammatical structure ( to + verb.)
2. After watching some Tv... This sentence lacks parallelism because the first verbs are in -ing form but the last one "read" does not follow this pattern.
3. The school was closed... This sentence uses parallel structure because it includes the expressions not only/but also (correlative conjunctions) that show grammatical consistency.
4. The ice was a greater problem... This sentence uses the preposition "for" to introduce two different details, which shows a parallel structure.
