Answer:
The sentence shown in the question above presents the figure of speech called a metaphor.
Step-by-step explanation:
The metaphor is the figure of speech that presents a comparison between elements. This comparison is made subjectively, creating a deep, reflective and poetic meaning. In the sentence shown in the question above, we can perceive the metaphor because the sentence shows that there are screams that are so desperate that they cause more agony than the heat, the thirst, the stinking stench and the suffocating breathlessness. In this case, the metaphor was used to compare the agony that uncomfortable, negative and bad elements can cause.
