First, you need to know what a gerund is. It refers to a word form that looks like a verb + ing. So here, the gerund phrase is <em>walking in the deep snow. </em>Also, you need to know that gerund is practically a noun in a sentence, meaning that it can function as either a subject or an object of a sentence. Here, the correct answer is the subject.
