Explanation:

Let’s break this down step by step. The question is all about figuring out what happens to a string of words when you push them through a “machine” that follows a hidden pattern.

First, spotting the rule:

- In the illustration, Step I and Step II knock out some words. By looking closely, you can see the pattern: remove words that start with vowels in each move until none are left.

- After all vowel-beginning words are out, the rest are rearranged in alphabetical order for the final steps.

Let’s apply this to your input:

- INPUT: FILES GRADE INSIDE AWARE ADVANCE PAIRS FOREIGN ALTER OVER TOWARDS

Step I:

- Remove words starting with a vowel: INSIDE, AWARE, ADVANCE, ALTER, OVER

- Left: FILES GRADE PAIRS FOREIGN TOWARDS

Step II:

- No words left that start with a vowel, so Step II is just: FILES GRADE PAIRS FOREIGN TOWARDS

Now, the question: Which word is third from the left in Step II?

- They are, in order: FILES (1), GRADE (2), PAIRS (3), FOREIGN (4), TOWARDS (5)

- So the third word is PAIRS

Let’s go over the options:

- Option 1, GRADE: that’s the second word.

- Option 2, PAIRS: third from the left.

- Option 3, FOREIGN: that’s fourth.

- Option 4, TOWARDS: that’s fifth.

- Option 5, None: nope.

Why?

- The “machine” kicks out anything starting with a vowel. What’s left: FILES, GRADE, PAIRS, FOREIGN, TOWARDS. Counting in order, PAIRS is the third. You nailed it.
