First we look at the six choices and eliminate any words that do not have a synonym in the list.
Let’s look at each word as we go down the list.
Severe could be a synonym to Extreme depending upon context.
Rainy has no synonym in the list
Unpredictable has no synonym in the list
Formulaic has no synonym in the list
Again Extreme is a synonym to Severe
Worsening has no synonym in the list
So, only two words are possible synonyms:
Rainy Unpredictable Formulaic
So, without even reading the question, we know the correct answers.
Let’s look at the whole question:
As global temperatures rise, wildfires, drought, and high electricity demand put stress on the nation’s energy infrastructure. And _________ weather, the leading cause of power outages and fuel supply disruption in the United States, is projected to worsen.
The two words we chose, Severe and Extreme make perfect sense in the context of the question. Rainy also fits in the blank and makes the passage make sense, but there is no synonym, so no other word would make the sentence have the same meaning. Unpredictable also fits, but again there is no synonym.
This method saves time and eliminates thinking about incorrect answers that fit into the passage well, but do not have a synonym among the answer choices.
