Mistake in marking of English Quiz 1

Dear parents,

My sincerest apologies for making a mistake in the marking of the English Quiz 1 for question 4.
The following is the question from the worksheet.

4. My sister and I ____________ the same pencil case.

(1) has

(2) is

(3) are

(4) have

The correct answer is: "(4) have". I had marked: "(1) has" as correct. I'm very sorry to everyone for the confusion the oversight has caused.

I will re-mark that question and award the marks accordingly.

Thank you all for your kind understanding.
