требовали
"Требовали" means "demanded" or "required" in English.
'Требовали' is derived from the verb 'требовать,' in the past tense, plural. Here it expresses a demand or strong request.
Ученики требовали объяснений от учителя.
The students demanded explanations from the teacher.
Again, 'требовало' comes from 'требовать,' this time in the past tense, singular (neutral gender). It signifies an expectation of compliance or adherence to rules or proposals.
Руководство требовало выполнения сроков.
The management demanded the deadlines to be met.
'Требовали' in this instance shows the action of insisting on an improvement or a change in quality, emphasizing dissatisfaction.
