Every recommendation she gives me is great ... c. … almost 50 per cent of US jobs are at risk from automation in the next 20 years. d. … none of us is prepared for the challenges of AI. 1. Why is 50 per cent singular in sentence (a) but plural in sentence (c)? 2. What are the subjects in sentences (b) and (d)? Are they singular or plural? Because in sentence (a), the part “50 per cent” is followed by the uncountable noun “time”, while in sentence (c), the part “50 per cent” is followed by the countable noun “job” in its plural form. In sentence (b), the part “Every recommendation” is the subject. In sentence (d), the part “ none of us” is the subject. Both are singular. Now look for more sentences following this rule in the reading passage, and summarise the use of subject-verb agreement in your own words. Nearly every job is potentially at risk in the long run.
