The theme in your sentence are pieces. Therefore, the verb must be plural to be compatible with the subject. The rule to which you refer applies only to partial words such as a quantity, some, all, etc., which are singular or plural, depending on what they refer to in the sentence that is normally the subject of the preposition. What about the “purpose” nomin? In this case, it is the subject of a proceeding. Now a process involves a variety of steps, practices and procedures, and therefore its purpose is complex. When I said “The purpose of the process is, (a, b, c and d.)” the text editor corrected to “goals.” Not sure I agree as one – d are all parts of the goal, not items you can choose. What do you think about it? However, if we remove the word “two” from your sentence, it would be written in formal American English as “fifty percent of mangoes are corrupted.” The object of your penalty is 50%. The fractions and percentages can be singular or plural depending on the object of the preposition. In this case, mangoes are the subject of the preposition of. Mangoes are plural; therefore, the use. In addition, our rule 1 of number writing says: “Spell out all the numbers starting a sentence.” With respect to the second sentence, our article 8 of the convention of reference and verb says: “The pronouns of everyone, of everyone, of anyone, of someone, of someone and of someone are singular and require singular verbs.” The grammatically correct phrase could be: “If all passengers please, stand,” or the heavy “If everyone would take their place, please.” What`s the right phrase: “A flood of Tribune employees sign up for buyouts” OR “A flood of Tribune employees registers for buyouts.” I saw that title online today, and it`s wrong to say “characters.” I think the “tide” refers to the pluralistic collective of “humans”, the verb must adapt to humans rather than floods, even if this is the object of preposition. I`d like to know if my intuition is correct. Thank you! Your sentence has two topics: Dr.
Jones and the team. Therefore, use the plural verb have. The object of the sentence is the plural-Nov questions, which is not a collective noun. Therefore, use the plural verb. When should we use the plural form of the collective noun? I mean, what if we were to say groups or classes? I also find the use of the plural form with collective subtantes problematic. One of the examples cited (the team was satisfied with its presentations) raises the question of the use of “sound” as a preposition pronoun. If “the team” is considered a singular, then the correct pronoun would be to give “he” “The team was happy with its presentations.” This seems to me to be quite acceptable, even if the prepositional name “presentations” is plural. This appears to run counter to the alleged principle that the case is based on plurality or not on prepositional-Nov. Our rule 7 of the subject-verbal agreement says: “Use a single verb with distances, periods, sums of money, etc., if they are considered a unit.” In addition, our rule 1 of number writing says: “Spell out all the numbers starting a sentence.” So writing 25 years of classes taught me… But I`m writing a friend`s book (a commentary on the book of the Galatians) and I came across a grammatical structure that is usual, but I just don`t know what`s considered right.
