He wrote his name on a __ of paper. a) side b) slip c) skirt d) sign

## Step 1The problem is a fill-in-the-blank type question, where we need to choose the most appropriate word to complete the sentence. The sentence is "He wrote his name on a __ of paper."## Step 2We need to consider the context of the sentence. The sentence is about writing a name on a piece of paper. The word that we need to fill in the blank should describe a type of paper that is suitable for writing.## Step 3Looking at the options, we can eliminate 'ide' and 'kirt' as they do not make sense in this context. 'Side' and 'kirt' are not types of paper.## Step 4Between 'lip' and 'ign', 'lip' is the most appropriate word. A 'lip' of paper is a small piece of paper, which is suitable for writing a name on.## Step 5'Sign' is not suitable in this context as it refers to a notice or a symbol, not a type of paper.
