Answer:
The element that does not contribute to the dreary mood in this short passage from the novel Bleak House by Charles Dickens. Is:
Infinitives
Step-by-step explanation:
There are two reasons behind this. First of all, infinitives explain the action and communicate that it is continuous. While it doesn't provide any stylistic device to the paragraph. This is important because stylistic devices are the ones used to provide the mood. Second, adjectives are used to explain the form of something, repetition to explain the importance of something, and punctuation to emphasize different parts of the text. While Infinitives only explain what something does.
