Explanation

Let's check with Venn diagrams:

Statements:

1. All investigators are trained officers. → Investigators ⊂ Trained Officers

2. Some trained officers are lawyers. → Trained Officers ∩ Lawyers ≠ ∅

3. No lawyer is an accountant. → Lawyers ∩ Accountants = ∅

Conclusions:

I. Some investigators are lawyers.

We know investigators are trained officers, and some trained officers are lawyers. But we don't know if those "some" overlap with investigators.  

→ Does not follow

II. No investigator is an accountant.  

We know no lawyer is an accountant. But we don't know if investigators are lawyers. Investigators could still be accountants since we have no direct link between investigators and accountants.  

→ Does not follow

III. Some trained officers are not accountants.

Some trained officers are lawyers. And no lawyer is an accountant.  

So those trained officers who are lawyers cannot be accountants.  

→ Follows

Answer: Only III follows

Explanation

T is fixed at 5th.

Q, S, T are one after another in sequence, so:

Q = 3rd

S = 4th

T = 5th

Left positions = 1st and 2nd for P and R.

Condition: P must be earlier than R.

So:

P = 1st

R = 2nd

P can be played First.

Explanation

Let's track Ahmed's movement:

Start at origin, facing North

1. Walks 8 km North → Now 8 km North of start

2. Turns Right → Now facing East. Walks 6 km East

3. Turns Right → Now facing South. Walks 8 km South  

   This brings him back to the same North-South line as start. Net: 8N - 8S = 0

4. Turns Left → Was facing South, left = East. Walks 3 km East

Final position:  

North-South: 0 km from start  

East-West: 6 km + 3 km = 9 km East of start
