Proofread the following article and correct its five subject-verb disagreements. 'This new technology is for everyone and will r
evolutionise the lives of millions of ordinary commuters. Cheaper than concrete or tarmac but just as durable, the new cycling paths absorbs light and re-emits it when they senses that it is required. They're one hundred percent environmentally-friendly.' The inventor, however, is less forthcoming when our conversation turns to how the product actually works. Despite a barrage of questions, the only thing he will admit to are that the key to this techno-wonder are a combination of recycled tyres (what else?) and a specially formulated light-emitting powder that charges during the day and glows at night.
A subject-verb agreement error
occurs when the number (whether or not something is singular or plural) of the
subject does not “agree” with the number of the verb. For instance, if a subject is singular, the verb
should be singular as well, and this is known as “agreeing.” If the subject is singular, but the verb is
plural, then this is known as a subject-verb agreement error (or subject-verb
disagreement). Below, the agreement
errors have been corrected to the proper number and appear in bold.
