Plural or singular noun in this case?

"The line graph illustrates the amount of goods which was delivered by road, water, rail and pipeline in the UK from 2000 to 2005".

Should I use "amount" or "amounts" in this case? (I am writing a report of a line graph with 4 lines, each of which depicts the amount of cargo transported by a particular mode of transport shown above)

Thanks in advance!


Solution 1:

Amount would be preferred because the following word (goods) ends with s .

As it is plural it will be which were and not which was.
