Does length be plural or singular with X and Y being a measure of A of B and B?
In the sentence:
X and Y are the lengths of A and B, respectively. Of the different things there are also X and Y.
If X is the length
- of A Y is the length
- of B then it is plural
or singular. Which is better?
What is a good business to be thankful for?
If we compare this with a sentence like “Pen and pencil are the tools of the trade” tools is used in plural form as opposed to singular form. Or in case of a dicky sentence like “Pen and pencil are the tools of the trade,” doesn’t. I would consider “lengths” as the correct word the
bsw is trying to correct.
