Which criterion would most likely designate a person who reads novels cover-to-cover in fewer than two hours as abnormal?

It's highly unlikely that any criterion would designate someone who reads novels cover-to-cover in fewer than two hours as abnormal.

Here's why:

* Reading speed is highly variable: People read at different paces. Some are fast readers, others are slower. There's no one "normal" speed.

* Novels vary in length: A short novella can be read in less than two hours, while a lengthy novel could take days or weeks.

* Reading comprehension: Just because someone reads quickly doesn't mean they're not comprehending the material. Some fast readers are also excellent at retaining information.

Instead of focusing on speed, it would be more relevant to consider:

* Understanding and retention: Can the person summarize the plot and characters accurately after reading?

* Enjoyment: Does the person find reading enjoyable, or are they rushing through books simply to finish them?

* Other factors: Does this reading speed impact their daily life or relationships negatively?

In conclusion, focusing on reading speed alone as a measure of abnormality is not appropriate. It's crucial to consider other factors and avoid making judgments based on a single, isolated behavior.
