Some people agree with the plan. / People agree with the plan.

I’d appreciate it if someone would answer my question. Thanks in advance.

Are the following 4 sentences all the same?

A: There are people who agree with the plan.

B: There are some people who agree with the plan.

C: Some people agree with the plan.

D: People agree with the plan.

I think A, B and C are the same in that part of the people are referred to, but D is different because “people” mean “people at large”, not part of the people.

you are right.

—Thank you beeesneees. There is one more I 'd like to know. What should I do if I am to mean that there are people who agree with the plan, and at the same time there are people who don’t agree with it. Do I have only to say A, B or C, or should I say that some people agree with the plan and others not?

If you say some people agree, you don’t have to state that some don’t. You can leave that to logic/common sense.

–--Thank you.
