Ex Input:
The four-leaf clover is a rare variation of the common three-leaf clover. According to traditional superstition, such clovers bring good luck, though it is not clear when or how that superstition got started. The earliest mention of ``Fower-leafed or purple grasse'' is from 1640 and simply says that it was kept in gardens because it was ``good for the purples in children or others''. A description from 1869 says that four-leaf clovers were ``gathered at night-time during the full moon by sorceresses, who mixed it with vervain and other ingredients, while young girls in search of a token of perfect happiness made quest of the plant by day''. The first reference to luck might be from an 11-year-old girl, who wrote in an 1877 letter to St. Nicholas Magazine, ``Did the fairies ever whisper in your ear, that a four-leaf clover brought good luck to the finder?''

Ex Output:
is there such a thing as a four leaf clover?


Ex Input:
Some notable performances in the Derby include Bobby Abreu in 2005, who won the Derby with a then-record 41 homers, including a then-record 24 in the first round. The first-round record was broken in 2008 by Josh Hamilton, who hit 28 home runs. Though Hamilton's performance was notable for the length of his home runs, he ultimately lost to Justin Morneau in a brief final round. The overall record was broken in 2016 by Giancarlo Stanton, who finished with a total of 61 home runs, defeating Todd Frazier in the final round. Only two participants, Yoenis Céspedes and Giancarlo Stanton, have won the Home Run Derby without being selected to the All-Star game itself.

Ex Output:
do you have to be an all-star to be in the home run derby?


Ex Input:
In association football, a substitute is a player who is brought on to the pitch during a match in exchange for an existing player. Substitutions are generally made to replace a player who has become tired or injured, or who is performing poorly, or for tactical reasons (such as bringing a striker on in place of a defender). Unlike some sports (such as American football, ice hockey or Kabaddi), a player who has been substituted during a match may take no further part in it.

Ex Output:

can you substitute an injured player in soccer?
