noun + gerund in one sentence

[ostap77]

"The prognostications and planning of an experiment have been very accurate."

I was told that it's grammatically incorrect to use the gerund and noun in one sentence.It should have been something like "The forecating and planning...." Is it so?

"Planning" is also a noun. Look it up in the dictionary.

-----------------------------
1- Why "an experiment"? Why not "the experiment"?
2- What do you mean by saying that prognostications of an experiment have been very accurate?
3- How much "planning" and "prognostications" are related to each other? I don't understand why you want to write these two words side by side!

To answer your question: Yes, you can use a noun and a gerund for the subject of a sentence.

His backtalk and skipping classes must stop.

But your sentence does not make sense. See Khosro's comments.

Yes.It sounds meaningless. I was trying to figure out if it's possible to use a gerung and a noun for the subject of a sentence. Thanks for clerifying.
