Afforestation has the purpose of restoring an area that has been destroyed due to previous overuse of the land. It helps in the reduction of soil erosion. Carbon dioxide (CO₂) traps heat and does not allow it to escape into the air. It is a greenhouse gas. Greenhouse gas is a gas in an atmosphere that absorbs and emits radiation within the thermal infrared range.

Correct Answer: Inaudible

Solution : The correct choice is the first option.

The word inaudible refers to a sound that is not able to be heard. In this context, it serves as a single word that succinctly captures the meaning of "a sound that cannot be heard".

The meanings of the other words are as follows:

• Audacious: This word describes someone bold, daring, or fearless.
• Autonomous: This term refers to something that operates independently or can function without external control.
• Delible: This word pertains to something that can be erased, blotted out, or easily removed.

Therefore, the most appropriate one-word substitute is inaudible.

Correct Answer:

Solution : As per the mirror image properties, closer things appear closer to the mirror in the reflection.
Here, according to the information provided, the mirror is placed on the right side of the figure (on line AB). So, the left side of the reflected image will appear as the right side, and the right side will appear as the left side. However, the top and bottom of the reflected image will remain the same.

Thus, the correct mirror image of the given figure will be –

Hence, the first option is correct.

Correct Answer: 56%

Solution : $840 = x\%$ of $1500$
$⇒ 840 = \frac{x}{100} × 1500$
$\therefore x=\frac{840}{15}= 56\%$
Hence, the correct answer is 56%.

Correct Answer: Ankit

Solution : Given:
(I) Five men Ankit, Bishal, Chandler, Daksh, and Joey are sitting at a horizontal table facing north.
(Left end ) _, _, _, _, _ (Right end ) (North Facing row)
(II) Ankit is to the immediate left of Daksh who is not at the corner. Joey is exactly in between Bishal and Chandler. Who is sitting at the leftmost end?
Ankit, Daksh, Bishal, Joey, Chandler.
or Ankit, Daksh, Chandler, Joey, Bishal. (Position of Bishal and Chandler not cleared)

So, Ankit is sitting at the leftmost end. Hence, the third option is correct.

Correct Answer:

Solution : As per the mirror image properties, closer things appear closer to the mirror in the reflection.
Here, according to the information provided, the mirror is placed on the right side of the figure (on line AB). So, the left side of the reflected image will appear as the right side, and the right side will appear as the left side. However, the top and bottom of the reflected image will remain the same.

Thus, the correct mirror image of the given figure will be –

Hence, the third option is correct.

Correct Answer: Stephen Hawking

Solution : The correct answer is Stephen Hawking.

Correct Answer: 82

Solution : Given:
BOOK is coded as 47, and PEN is coded as 38. 

Add the positional value of the alphabets and the number of the alphabets of the given word to obtain a code.
BOOK→2 + 15 + 15 + 11 = 47; 43 + 4 = 47
PEN→16 + 5 + 14 + 3 = 35; 35 + 3 = 38
Similarly, NOTEPAD→14 + 15 + 20 + 5 + 16 + 1 + 4 = 75; 75 + 7 = 82

So, NOTEPAD is coded as 82. Hence, the second option is correct.
