Let's analyze each of these questions step by step.

Q11:

Statements:

• $M \geq T < V$
• $U < V < X$
• $Z \geq Y \geq X$

Conclusions:

1. $T < Z$
2. $U < Y$
3. $M > X$
4. $M \geq X$

Analysis:

• From the statements $M \geq T < V$ and $Z \geq Y \geq X > V > T$, it follows that $T < Z$, so conclusion I is true.
• $U < V < X$ and $Z \geq Y \geq X > U$ imply that $U < Y$, so conclusion II is true.
• $M \geq T$ and $X > V > T$, but there is no direct relationship between $M$ and $X$ that allows us to conclude $M > X$, so conclusion III does not follow.
• $M \geq T$ and $T < X$, $M \geq X$ is possible but not certain, so conclusion IV does not follow.

Answer: 2) Only conclusion I and II follow.

Q12:

Statements:

• $W \leq A \leq K = N$
• $D \leq A \leq U = L$
• $G > L$

Conclusions:

1. $W < G$
2. $U \geq W$
3. $D \geq N$
4. $A \leq N$

Analysis:

• $G > L = U \geq A \geq W$, so $W < G$, thus conclusion I follows.
• $U = L \geq A \geq W$, so $U \geq W$, thus conclusion II follows.
• $N = K \geq A \geq D$, so $D \geq N$ does not follow.
• $A \leq K = N$, so $A \leq N$ follows.

Answer: 5) Only conclusions I, II, and IV follow.

Q13:

Statements:

• $N < T \leq O$
• $F > N \geq E = I > R$
• $R \geq Y$

Conclusions:

1. $Y < O$
2. $T < F$
3. $T \geq F$
4. $R < O$

Analysis:

• $N < T \leq O$ and $R \geq Y$, $F > N \geq E = I > R \geq Y$, so $Y < O$ follows.
• $T \leq O > N$, and $F > N$, but no direct comparison between $T$ and $F$, so $T < F$ does not follow, and $T \geq F$ does not follow either.
• $R < O$ could be true since $R \geq Y < O$, so conclusion IV follows.

Answer: 1) Only conclusions I and IV follow.

Q14:

Statements:

• $I \geq N \geq O = X$
• $D \geq J \geq I = E$

Conclusions:

1. $O < D$
2. $X = D$
3. $D \geq N$
4. $E \geq X$

Analysis:

• $D \geq J \geq I \geq N \geq O = X$, so $O < D$ follows.
• $X$ is equal to $O$, but not directly equal to $D$, so $X = D$ does not follow.
• $D \geq J \geq I \geq N$, so $D \geq N$ follows.
• $E = I \geq N \geq X$, so $E \geq X$ follows.

Answer: 3) Conclusions I, III, and IV follow.

Q15:

Statements:

• $X \geq T$
• $Z < K < H$
• $F = Q$
• $T < Z$
• $F > H$

Conclusions:

1. $T < F$
2. $Q > K$
3. $Z < F$

Analysis:

• $F > H > K > Z > T$, so $T < F$ follows.
• $F = Q$ and $Q > H > K$, so $Q > K$ follows.
• $F > H > K > Z$, so $Z < F$ follows.

Answer: 5) All conclusions I, II, and III follow.
