'This new technology is for everyone and will revolutionise 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 (whatelse?) and a specially formulated light-emitting powder that charges during the day and glows at night.

The subject-verb agreement errors that must be fixed are: The word "absorbs" must be changed to "absorb;" the word "re-emits" should be changed to "re-emit;" the word "senses" should be changed to "sense."

In addition, the following subject-verb agreement errors must be corrected:

The sentence "the only thing he will admit to are that the key..." should change the verb "are" to "is."
The sentence "... the key to this techno-wonder are a combination of recycled tyres..." must also change the verb "are" to "is."

What is a subject-verb agreement error?

It is a grammatical error that damages the integrity of the language and the correct connection between words and can compromise the coherence and cohesion of the entire text. When this kind of error happens, the subject of the sentence is not harmonically aligned with the verb. This compromises the meaning of the text and hinders reading, in addition to not allowing the flow of the text.

It is important to remember that the subject is the word that is promoting or suffering the action of a verb, while the verb is the word that indicates an action that is happening.
