Q: passage: Despite the fact that Brenda never appeared on the screen, she was nonetheless present during occasional discussions during the following six seasons of the series. The most significant among them is her reconciliation with Dylan, who was going to move in with her. It is assumed that they were together for most episodes of the seventh and eighth seasons of the series, as during an episode of season 8 where it is learned that Dylan's half-sister was saved from a life of prostitution and then left to live with Dylan and Brenda in London and Kelly and Brandon mentioned going to visit them for part of their honeymoon. Later, when Dylan returned in season 9, he told his friends that he and Brenda had separated two years earlier. However, it frees Dylan to resume his relationship with Kelly.

Q: passage: The Argentine Currency Board pegged the Argentine peso to the U.S. dollar between 1991 and 2002 in an attempt to eliminate hyperinflation and stimulate economic growth. While it initially met with considerable success, the board's actions ultimately failed. In contrast to what most people think, this peg actually did not exist, except only in the first years of the plan. From then on, the government never needed to use the foreign exchange reserves of the country in the maintenance of the peg, except when the recession and the massive bank withdrawals started in 2000.
 question: is the argentine peso pegged to the dollar?

No
