Problem: Text: This is a list of all penalty shoot-outs that have occurred in the Finals tournament of the FIFA World Cup. Penalty shoot-outs were introduced as tie-breakers in the 1978 World Cup but did not occur before 1982. The first time a World Cup title was won by penalty shoot-out was in 1994. The only other time was in 2006. By the end of the 2018 edition, 30 shoot-outs have taken place in the World Cup. Of these, only two reached the sudden death stage after still being tied at the end of ''best of five kicks''.

Problem: Text: Also, great variety is seen in the Aussie's eye color, and they are often heterochromatic. An early nickname for the breed was ''ghost-eye dog''. Aussie eyes may be any shade of brown, or blue; they may have two differently colored eyes, or even have bicolored or ''split eyes'' (for example, a half-brown, half-blue eye), which appear to be linked to the merle coloration. Merled eyes occur, as well, where one color is mixed in and swirled with another. Any combination of eye color is acceptable in the breed standard, so long as the eyes are healthy. In general, however, black Aussies (self, bi-color, or tri-color) tend to have brown eyes, while red (self, bi-color, or tri-color) Aussies tend to have amber eyes, though these Aussies may also carry the blue-eyed gene.

Question: do all australian shepherds have different colored eyes?
A: no
