The excerpt is an example of inductive reasoning because the authors formulate a generalization by studying specific examples.
Here are some examples of those examples:
* Unseasonably pleasant weather inspires people to pay at a higher rate. Unseasonably cold weather, meanwhile, makes people cheat prolifically; so do heavy rain and wind.
* The high-cheating holidays are fraught with miscellaneous anxieties and the high expectations of loved ones.
We can say that this information is real since it has been seen year after year the same effect on people.
The other options are not correct because they already start from a generalization or never get to one, meanwhile, the correct one creates that generalization.
