For the last sentence of the stimulus, since we use the contrapositive, wouldn't it be "requests cancellation beforehand OR in writing"?

Was stuck between D and E, but decided to go with answer choice E.

Someone please explain why E is wrong

­In the course of his reading, George Orwell probably encountered certain storytelling conventions over and over again, and these are the devices he would have most likely used in his work. That is why it does not follow that, even though his 1984 resembles other books of its

futuristic genre, Orwell read those books; it is possible that he and the other authors were simply drawing on the same body of literary conventions.

(D) A recent film that involves car chases, explosions, and clever villains is not necessarily directly influenced by other films of the action genre.

(E) A historical romance novel does not fit into its literary genre unless it employs certain kinds of conventions.

how do I print it? there's no print option

How do you guys drill?

I'm looking to improve on LR overall, and I'm not sure if I should lump together different question types in one drill. If I do this, how many questions should I have in one mixed drill and how do I divide them based on their difficulty range?

Flaw and weaken are two question types I tend to get incorrect, should I drill them separately? If so, how many questions should I add in my drill and how many of each based on their difficulty range?
