good morning sir
please clear my confusion
He erases the evidence by rubbing.(he rubs and evidence is erased)
there is two action is performed but confusion is that if he rubs evidence then who erased it? because erasing is result but who is doer of result.
we can make hundreds of sentences like this.
He erasing the evidence by rubbing.
She kills the worms by stepping on them.
The job was completed early by working seven days a week.
Let's move on to the second example, which is a possible sentence: She kills the worms by stepping on them. There is only one action - she steps on the worms. As a result of this, the worms die. We can say, therefore, that she kills the worms. We can also say that the worms cease to live. We could say perhaps that she commits lumbriciciniide. We could perhaps think of several other ways of talking about this brutal act. There is no confusion.
