Este mazo se modificó al incorporarlo: Each multiple-choice question from the database was turned into a single card, "question -> full answer": the three distractors are dropped, as they make no sense in active recall. Removed as well: questions that refer to the list of choices or to a missing picture, questions whose answer is tied to a moment in time (including "best-selling" and other record superlatives), true-or-false items, restatements of a question already in the pack, pairs of cards that are the same fact asked in both directions, and entries whose wording contains a spelling mistake. HTML entities served by the API were decoded and invisible whitespace stripped. No question or answer text was rewritten.

Compartir igual: cualquier versión modificada que redistribuyas debe llevar la misma licencia.
