Which verb in bold is the correct?

Neither.

A case in point is.... (one thing)
Cases in point are... (multiple things)

"the subsidies and other forms of domestic support" are multiple things. You could rephrase the sentence to make one singular case in point e.g. "A case in point is the provision of subsidies and other forms of domestic support to various industries that developed countries are contemplating."

Tes is right of course Tang, but I don't think she actually quite answered your q, did she

No expert at all, however, I'd've used "is;" tho of course Tes' version is better

Now tho I hope someone will want to discuss my placement of the semi

Tes didn't answer my question. He rephrased it.

ops Tang you gotta forgive my editing; thought I was quicker'n that

...with apologies again to Tes for the sex confusion

Is the OP a forced response question?

I have already told you I am not a "she", I thought.

I answered the question in the first line of my reply which reads "Neither".


See above.

I replied that neither 'is' nor 'are' is the correct verb. I then explained when 'is' would be appropriate, and when 'are' would be appropriate. As it stands, the sentence cannot be made right merely by choosing one of the two verb forms. It therefore needs revising. I showed an example of how this might be done. It is not the only way the sentence could be revised.

I would not have put it inside the quotes like that.

A case in point is/are the subsidies and other forms of domestic support to various industries that developed countries are contemplating.

subsidies and forms / are/ case in point

A single case in point is a single instance or example that illustrates what is being discussed. Multiple cases in point are multiple instances or examples. The original question that started this thread was: "A case in point is/are the subsidies and other forms of domestic support to various industries that developed countries are contemplating." We are asked to say whether 'is' [singular] or 'are' [plural] is the right form of the verb 'to be'. You might say that because there are multiple things following the verb, the right form is 'are', but if you do, you have to go back before the verb and fix the singular 'A case'. Alternatively, if you say that, because the sentence starts with a singular 'A case', the correct form of the verb is 'is', then you have to go forward past the verb and fix the plural items somehow.

I disagree.

'a case in point" is an idiom.

How about if we use another introductory opener, like:

To be considered are the subsidies . . . and . . . forms

Not that much of an idiom.

Most profound apology Tes. At 85 my mind wanders
