There is something at the end of the problem, one of them that is best placed to leave two parallel examples, when we could do much more: A. One in three new teachers left the profession in three years. B. One third of new teachers have left their profession in three years. The subject-verbal agreement is when the subject and the verb correspond in number/plurality. On the other hand, the disagreement between the subject and the word is simply the absence of this agreement. They therefore record „store“ is the plural verb associated with the plural theme. The first place is a singular verb according to a plural subject. The second places a plural verb according to a singular subject. If two options are presented as alternatives and not as a combination, with or not, a singular verb is appropriate, as it applies only to the first option: „The implementation of simplified solutions based on symptomatic causes or a single cause, if there are multiple causes of interaction, is very likely that failure and disappointment will end.“ There is therefore a disagreement in the number/plurality. When creating sentences, authors must ensure that verbs are bent to match the subject – the word or phrase to which the verb refers – which is not necessarily the neighbouring subprov. The following sentences, which are discussed and revised under the examples, show the different pitfalls that can be encountered with this theme. The theme of a sentence must correspond to the verb of the sentence: in sentences like this, where a sentence refers to a part of a whole in which the part is one, the verb should be unique: „Almost one in three companies spends less than a million dollars a year to comply with the regulation.“ The program verb does not refer to this word, but to demonstration – it is the act of protesting, it is not the programs that have provided the support mentioned here that has the correct form of verb: „The demonstration of effective continuous monitoring programs has also helped leading institutions meet increased regulatory expectations.“ In sentence A, „One“ is the object of the sentence, and one of them is singular.
There is no way to go. Some people find ways to argue that „none“ is not singular, but „none is“ acceptable, but I absolutely cannot see it. If „one“ is singular, „zero“ is also singular. In sentence B, we do arithmetic in the form of words, and „a third“ is multiplication. If z.B. the number of new teachers is 999, then (1/3) x (999) – 333, which is still plural. Sometimes collective nouns can be particularly confusing. If a single name implies that there are several people, the verb should be singular or plural?! The answer is simple.
