Fill in the blank by selecting the correct option from those given in the brackets. The narrator references canaries and miners in order to ____. (highlight the historical use of canaries as warning systems/explain the reason that caused Claribel to faint suddenly)
highlight the historical use of canaries as warning systems
Explanation
The narrator mentions that 'miners used to carry canaries down to warn them of gas' to draw a parallel between the historical practice and the current situation. This reference helps explain why Claribel's fainting is significant—she is acting as an early warning system for dangerous air conditions, just as canaries did in mines. The reference provides context for understanding Claribel's role as an unwitting safety mechanism.
