In above blog it says ...
1). Compound subjects
i). When the subject of a sentence is formed of two or more nouns or pronouns connected by "and",we use a plural verb.e.g
Gold and silver are precious metals.
gold and silver--(plural subject)
Note: Exception to the above rule is --- when the compound subjects are preceded by “every,” “no,” or “nothing”
Any example of the exception ?
It also says
Collective nouns are singular when they refer to a unit and plural when they refer to the individuals or elements of a unit.
Example : The committee meets every friday evening.
Committee---(it is singular)
meets---(verb with s- ending)
Any example of collective noun as a plural subject
