I have just a not about word : family
Family it is collective noun ,so
It describes a group of people like the words team .
The question is :
Is it singular or plural .
Is family IT or THEY.
?
Are we can say
His family is big
Or
Their family are big
So the answer depends on whether you are using British or American English.
Very generally ,in British English , collective nouns are commonly treated as a plural .
While the American English use it as a singlar word .
And in your exemple you used Family as a singlar . because you puted the aticle A.
