Explanation

From the given information:

1. A reaches before B → A < B

2. B reaches before D → B < D  

3. C reaches before D → C < D

Combine 1 and 2: A < B < D  

Combine with 3: C < D

So D is after both B and C. That means D cannot be last because someone is definitely behind D? Wait no — "last" means finishes after everyone.

From A < B < D, D is after A and B.  

From C < D, D is after C too.

So D finishes after A, B, and C.  

Therefore D certainly finishes last.

Explanation

Let's place them one by one:

1. Lahore is not to the East of Karachi

   So Lahore is West / North-West / South-West of Karachi.

2. Islamabad is to the North of Lahore 

   So Islamabad is directly North of Lahore.

3. Peshawar is to the West of Islamabad 

   So Peshawar is West of Islamabad.

Now combine:  

Karachi → Lahore is somewhere West.  

Lahore → Islamabad is North.  

Islamabad → Peshawar is West.  

So from Karachi, go West to Lahore area, then North to Islamabad, then West again to Peshawar.

That puts Peshawar to the North-West of Karachi.

Explanation

Let's check the alphabet positions:

B = 2  

E = 5  

I = 9  

N = 14  

T = 20  

? = 

Differences:  

5 - 2 = +3  

9 - 5 = +4  

14 - 9 = +5  

20 - 14 = +6  

Pattern: +3, +4, +5, +6... so next should be +7

20 + 7 = 27

Alphabet wraps after 26, so 27 - 26 = 1

1st letter = A

Explanation

Let's find the pattern in B, E, J, Q, Z, ?

Look at alphabet positions:

B = 2

E = 5

J = 10  

Q = 17

Z = 26

Now check the differences:

5 - 2 = +3

10 - 5 = +5  

17 - 10 = +7

26 - 17 = +9

The differences are +3, +5, +7, +9... odd numbers increasing by 2

Next difference should be +11

26 + 11 = 37

Alphabet wraps around after 26. So 37 - 26 = 11

11th letter = K

• Overwatering harmed tree species that required less water.
• Planting trees improved air quality and reduced summer temperatures.
• However, giving too much water caused some trees to die.
• This shows that proper tree care is as important as tree planting.
• The paragraph does not suggest that trees cannot survive in cities or that planting trees reduces rainfall.

Explanation

Six people A, B, C, D, E, F sit around a circular table facing center.

1. C is opposite A.  

2. E is opposite B.  

3. D is second to the left of C.  

4. A is second to the right of B.  

From 1: Place A and C opposite each other.  

From 2: Place B and E opposite each other.  

From 3: D is 2nd left of C.  

From 4: A is 2nd right of B.  

Arranging all conditions, the order clockwise is:  

B, A, D, C, E, F  

Check:  

A is 2nd right of B ✓  

C opposite A ✓  

D 2nd left of C ✓  

E opposite B ✓  

Now check neighbors of F: B and A.  

So F is sitting between B and A.
