QUES: While these few hard rock bands managed to maintain success and popularity in the early part of the decade, alternative forms of hard rock achieved mainstream success in the form of grunge in the US and Britpop in the UK. This was particularly evident after the success of Nirvana's Nevermind (1991), which combined elements of hardcore punk and heavy metal into a "dirty" sound that made use of heavy guitar distortion, fuzz and feedback, along with darker lyrical themes than their "hair band" predecessors. Although most grunge bands had a sound that sharply contrasted mainstream hard rock, several, including Pearl Jam, Alice in Chains, Mother Love Bone and Soundgarden, were more strongly influenced by 1970s and 1980s rock and metal, while Stone Temple Pilots managed to turn alternative rock into a form of stadium rock. However, all grunge bands shunned the macho, anthemic and fashion-focused aesthetics particularly associated with glam metal. In the UK, Oasis were unusual among the Britpop bands of the mid-1990s in incorporating a hard rock sound.
What form of music did Stone Temple Pilots turn into mainstream hard rock?

ANS: unanswerable


LeToya Luckett and Roberson became unhappy with Mathew's managing of the band and eventually were replaced by Farrah Franklin and Michelle Williams. Beyoncé experienced depression following the split with Luckett and Roberson after being publicly blamed by the media, critics, and blogs for its cause. Her long-standing boyfriend left her at this time. The depression was so severe it lasted for a couple of years, during which she occasionally kept herself in her bedroom for days and refused to eat anything. Beyoncé stated that she struggled to speak about her depression because Destiny's Child had just won their first Grammy Award and she feared no one would take her seriously. Beyoncé would later speak of her mother as the person who helped her fight it. Franklin was dismissed, leaving just Beyoncé, Rowland, and Williams.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How long was Beyonce depressed?
Ah, so.. a couple of years


Question: The dates are generalizations, since the periods and eras overlap and the categories are somewhat arbitrary, to the point that some authorities reverse terminologies and refer to a common practice "era" comprising baroque, classical, and romantic "periods". For example, the use of counterpoint and fugue, which is considered characteristic of the Baroque era (or period), was continued by Haydn, who is classified as typical of the Classical era. Beethoven, who is often described as a founder of the Romantic era, and Brahms, who is classified as Romantic, also used counterpoint and fugue, but other characteristics of their music define their era.
Try to answer this question if possible: What composer continued the counterpoint and fugue?
Answer: Haydn


Input: Read this: Hokkien has one of the most diverse phoneme inventories among Chinese varieties, with more consonants than Standard Mandarin or Cantonese. Vowels are more-or-less similar to that of Standard Mandarin. Hokkien varieties retain many pronunciations that are no longer found in other Chinese varieties.
