References to a married couple can pose problems. When referring to the two people in the context of their wedding, treat couple as plural since they are individuals entering into a marriage.
* The couple were married last Saturday.
* After the wedding, when the two people are acting as a unit, treat couple as singular.
* That couple has been married for more than twenty years.
* Each couple has volunteered to participate in the literacy campaign.

- The data obtained after two months of experimentation is now being analyzed.
(Here
data means “information.”)
- The data assembled by six researchers are now being compared.
(Here
data refers to several distinct bits of information.)
