In the following questions, a sentence is given with

Solution

For the 1st blank: "threaten" is the most suitable option. The word "threaten" conveys a sense of imminent risk or danger, which aligns well with the context of energy disruptions potentially destabilising regions. While "continue" suggests persistence, it does not capture the severity implied in the sentence. Similarly, "fail" is contextually incorrect, as it does not align with the idea of energy disruptions causing destabilisation. For the 2nd blank: "driving" is the best choice because it denotes actively causing or pushing forward an outcome, which in this case refers to social unrest and migration. While "escalating" implies an increase in intensity, it does not fit grammatically or contextually with the preceding phrase. Words like "eliminating" and "sparking" are also unsuitable, as they do not reflect the gradual and ongoing effect described in the sentence.
