What does the underlined modal auxiliary suggest in the following sentences (Q. Nos. 83 & 84) ? The conservatives should win the next election.

Question

Accepted Answer

The correct option is 2:
Probability. The modal auxiliary verb "should" has several uses in English, but when it is used in the context of predicting a future event based on current knowledge or expectation, it expresses a moderate degree of probability or likelihood. In the sentence, "The conservatives should win the next election," the speaker is not issuing a command or expressing a moral duty; instead, they are offering a calculated opinion or a strong prediction that the conservatives are the likely winners, perhaps based on polls, historical trends, or current political climate. This usage of "should" suggests that the expected outcome is high, though not 100% certain, perfectly aligning with the concept of probability.

The incorrect option is 1: Obligation. "Should" typically expresses obligation or duty (like 'You should finish your homework'), but in this sentence, the victory of the conservatives is a predicted event, not a moral or legal requirement placed upon them. The modal is focused on the certainty of the outcome, not the necessity of the action.

The incorrect option is 3: Desirability. While the speaker may personally desire the conservatives to win, the primary function of "should" in this predictive structure is to convey likelihood, not just preference. If the sentence merely expressed desire, it would more often use modals like "I hope they win" or "I wish they would win."

The incorrect option is 4: Conjecture. Conjecture refers to forming an opinion or theory without proof or sufficient evidence, which suggests a weaker degree of certainty. The use of "should" generally implies a stronger, more reasoned expectation than a mere guess or speculation, placing it firmly in the category of probability.
