For collective nouns such as group, jury, family, public, population, the verb can be singular or plural, depending on the intention of the author. The subject of the sentence is the rays (plural head noun), hence the conb plural. If the two nouns are connected by a singular idea and represent it, then the verb is singular. In Hungarian, verbs have a polypersonal agreement, which means that they agree with more than one of the arguments of the verb: not only with its subject, but also with its object (accsative). A distinction is made between the case in which there is a particular object and the case in which the object is indeterminate or there is no object at all. .
