[EX Q]: Passage: List of Super Bowl champions -- The Pittsburgh Steelers (6--2) have won the most Super Bowls with six championships, while the New England Patriots (5--5), the Dallas Cowboys (5--3), and the San Francisco 49ers (5--1) have five wins. New England has the most Super Bowl appearances with ten, while the Buffalo Bills (0--4) have the most consecutive appearances with four (all losses) from 1990 to 1993. The Miami Dolphins are the only other team to have at least three consecutive appearances: 1972--1974. The Denver Broncos (3--5) and Patriots have each lost a record five Super Bowls. The Minnesota Vikings (0--4) and the Bills have lost four. The record for consecutive wins is two and is shared by seven franchises: the Green Bay Packers (1966--1967), the Miami Dolphins (1972--1973), the Pittsburgh Steelers (1974--1975 and 1978--1979, the only team to accomplish this feat twice), the San Francisco 49ers (1988--1989), the Dallas Cowboys (1992--1993), the Denver Broncos (1997--1998), and the New England Patriots (2003--2004). Among those, Dallas (1992--1993; 1995) and New England (2001; 2003--2004) are the only teams to win three out of four consecutive Super Bowls. The 1972 Dolphins capped off the only perfect season in NFL history with their victory in Super Bowl VII. The only team with multiple Super Bowl appearances and no losses is the Baltimore Ravens, who in winning Super Bowl XLVII defeated and replaced the 49ers in that position. Four current NFL teams have never appeared in a Super Bowl, including franchise relocations and renaming: the Cleveland Browns, Detroit Lions, Jacksonville Jaguars, and Houston Texans, though both the Browns (1964) and Lions (1957) had won NFL championship games prior to the creation of the Super Bowl.
Question: have the browns ever won a super bowl
[EX A]: 0

[EX Q]: Passage: Estrogen -- Estrogens are synthesized in all vertebrates as well as some insects. Their presence in both vertebrates and insects suggests that estrogenic sex hormones have an ancient evolutionary history. The three major naturally occurring forms of estrogen in females are estrone (E1), estradiol (E2), and estriol (E3). Another type of estrogen called estetrol (E4) is produced only during pregnancy. Quantitatively, estrogens circulate at lower levels than androgens in both men and women. While estrogen levels are significantly lower in males compared to females, estrogens nevertheless also have important physiological roles in males.
Question: is there such a thing as natural estrogen
[EX A]: 1
