Final answer:
Without additional context or reference to a specific book or story, it is not possible to provide the names of the 3 boys Jake hung out with, referred to as 'the Death Rays'.
Step-by-step explanation:
The question does not provide enough context to accurately answer who the 3 boys named 'the Death Rays' are that Jake hung out with. The names and the group 'the Death Rays' could be from a book, a story, or other forms of media, but without specific details or reference material, it is impossible to provide the names of the characters.
To answer such a question, additional information about the source material is required, such as the title of the book, the author, or any specific context within which the characters exist.
The names of the 3 boys Jake hung out with were not provided in the question. Therefore, we don't have specific names to provide. However, in general, you could come up with fictional names for the Death Rays such as Max, Ethan, and Liam.
