Let's examine other options too, 1. z > w, y is less than x and z is less than y so, obviously z is less than x. On the other hand w is also less than x. But we can not say for sure that z is greater than w. z can be greater than w or can be smaller than w. So this option is not the answer. 2. y > w, in the same way of option 1, here y can be either greater or less than w, so this is also not the anwer we are looking for. 3. y = w, this is also not necessarily always true, y can be less or grater than w too, so this can not be the answer. So, the correct answer choice here is option 4.
