(a)

Interpretation Introduction

Interpretation:

Whether the mentioned conclusions can be agreed or not has to be explained.

Concept Introduction:

$C{O}_2$as a toxic gas:

The contribution of the ${\text{CO}}_{\text{2}}$ gas in the atmosphere is less than $\text{1}\text{percent}$. ${\text{CO}}_{\text{2}}$ becomes a poisoning gas when its level increases in the atmosphere. So, ${\text{CO}}_{\text{2}}$ becomes toxic at its higher concentrations in the atmosphere.

(b)
