Explanation:

Let’s break this down quickly:

- We want: P > S. So, whatever symbols we use between P, Q, R, S, should guarantee that P is definitely greater than S.

- Now, look at the options:

Option 1: >, =, >

So, P > Q = R > S — which means:

P is greater than Q,

Q equals R,

R is greater than S.

But since Q = R, this becomes P > R, and both Q/R > S, so P is definitely greater than S.

This works.

Option 2: =, <, =

P = Q < R = S – P could actually be less than S. No guarantee.

Option 3: <, =, <

P < Q = R < S – P is less than S. Not what we want.

Option 4: <, =, >

P < Q = R > S – P could be less than Q/R, which are greater than S. So P could be less than S.

Option 5: <, <, =

P < Q < R = S – Again, P could be less than S. No good.

So, here’s what this means:

Option 1 is the only one that guarantees P > S.
