Are There Any Errors?

I don't know why the picture was not attached at the first post. Please check it here.

There are no mistakes in the instructions that I can see.

Did you get the right answer?

Yes, it is easy to figure out the answer for me. The answer is letter A. ; )

But I confuse this sentence: "There are 2 balls marked with each letter."

May I change it to: There are 2 balls marked with the same letter?

Thanks

tungnguyenMay I change it to: There are 2 balls marked with the same letter?

There are 10 balls all together, and this says only that two of them are marked with the same letter. It says nothing about the other 8 balls.

But with 'each', you know there are two marked with the same letter A, two marked with the same letter B, and so on.

I think your version would be understood, but just in case, I'd leave the sentence as it was originally.

Thanks for your explanation, it helped me a lot.

By the way, the word "differently" is correct in the following picture?

No. That's a very strange sentence!

Here's one way you can fix it:

Lisa has four dogs, each with a different weight.
