re: The World May Never Eradicate ... page 3
Consider this sentence, please:
1) The world may never eradicate coronavirus, but it could get it under control.
2) The world may never eradicate coronavirus, but it might get it under control.
What is the difference between 1) and 2)?
In general, What's the difference between "might" and "could" when it comes to talking about a possibility?

But some people might consider sentence a) to be a mixed conditional. Am I right?
You say: I'd call it a mixed conditional.
Which one of these do you mean?
Your child may do better if she got/had a different teacher.
Or
Your child might do better if she got/had a different teacher.
By a "mixed conditional" here, you mean the result clause is that of a "first conditional" and the conditional clause is that of a "second conditional". Am I right?
Yes, I suppose that interpretation is also possible. Just not for me.
This one:
Your child may do better if she got/had a different teacher.
Yes.

One more question:
1) I might go to the beach if the sun was/were shining.
2) I might go with you to the market if I wasn't/weren't ill.
3) I might do better if I had a different teacher.
4) I might buy a 20-room mansion if I won the lottery.
Do sentences 1-4 need commas before the "if"s?
5) I could go to the beach if the sun was/were shining.
6) I could go with you to the market if I wasn't/weren't ill.
7) I could do better if I had a different teacher.
8) I could buy a 20-room mansion if I won the lottery.
Do sentences 5-8 need commas before the "if"s?
1) and 2) strike me as "real" (not "hypothetical") future possibilities, so the present tense seems more appropriate in the if-clause.
3) and 4) could go either way (if I have/had; if I win/won), but it's easier for me to imagine these as hypothetical so I expect just what you've written.
All of these with 'could' sound fine to me.

c) If the astronaut momentarily lost radio contact with earth, the whole mission could be ruined.
Would you call sentence c) a mixed conditional ("could" = "M-possibility") or would you call it a pure second conditional?
Here "ruined" is an adjective or a verb?
I hear it as a pure second conditional.
I hear it as a verb ("that would ruin the whole mission"), but it's a bit ambiguous.

Isn't this a pure first conditional and not a mixed 1st/2nd conditional?
If you don't hurry, you could miss the train
That sounds like a reasonable interpretation, could being the equivalent of may or might here.
Nevertheless, this is a matter of opinion, and we are each entitled to our own opinions on these matters. There is no standard terminology that applies definitely to conditionals that are not purely the WOULD and WOULD HAVE types. Should we classify them by the forms or by the meanings? And does that even matter?
Besides, I wonder what benefit accrues from being able to place labels on conditional sentences, if any. Does it contribute to fluency in speaking or writing? I doubt it.
CJ
So the difference of opinion is because some might consider the sentence: "If you don't hurry, you could miss the train" a first conditional, by looking at the paraphrase for "could" here, namely: "maybe you will" and others might consider it a mixed conditional just because it uses "could", which is normally considered "unreal/hypothetical". Is this what you mean?
