Answer: However, the grunge music of the 1990’s took me a while to appreciate.
Step-by-step explanation: According to the given paragraph, apostrophes are used in three cases: to indicate a possessive case (for example "Eddie Vedder's voice" and "grunge's appeal), when a letter or letters have been removed (for example "I've" because it is an abbreviation of "I have") and the third one is to indicate that a lowercase letter is plural, therefore the sentence that violates the guidelines for apostrophes is "However, the grunge music of the 1990’s took me a while to appreciate" because it should say "1990s."
