[Q]: Extract the answer to the question from the following context. Question: What can be a plants defense? Context: Judging relationships based on shared characters requires care, since plants may resemble one another through convergent evolution in which characters have arisen independently. Some euphorbias have leafless, rounded bodies adapted to water conservation similar to those of globular cacti, but characters such as the structure of their flowers make it clear that the two groups are not closely related. The cladistic method takes a systematic approach to characters, distinguishing between those that carry no information about shared evolutionary history – such as those evolved separately in different groups (homoplasies) or those left over from ancestors (plesiomorphies) – and derived characters, which have been passed down from innovations in a shared ancestor (apomorphies). Only derived characters, such as the spine-producing areoles of cacti, provide evidence for descent from a common ancestor. The results of cladistic analyses are expressed as cladograms: tree-like diagrams showing the pattern of evolutionary branching and descent.

[Q]: Extract the answer to the question from the following context. Question: where did she offend puerto rico? Context: In September 1993, Madonna embarked on The Girlie Show World Tour, in which she dressed as a whip-cracking dominatrix surrounded by topless dancers. In Puerto Rico she rubbed the island's flag between her legs on stage, resulting in outrage among the audience. In March 1994, she appeared as a guest on the Late Show with David Letterman, using profanity that required censorship on television, and handing Letterman a pair of her panties and asking him to smell it. The releases of her sexually explicit films, albums and book, and the aggressive appearance on Letterman all made critics question Madonna as a sexual renegade. Critics and fans reacted negatively, who commented that "she had gone too far" and that her career was over.

[Q]: Extract the answer to the question from the following context. Question: Who ruled England in 1550? Context: In England, the 16th-century European Reformation resulted in a number of executions on charges of heresy. During the thirty-eight years of Henry VIII's reign, about sixty heretics, mainly Protestants, were executed and a rather greater number of Catholics lost their lives on grounds of political offences such as treason, notably Sir Thomas More and Cardinal John Fisher, for refusing to accept the king's supremacy over the Church in England. Under Edward VI, the heresy laws were repealed in 1547 only to be reintroduced in 1554 by Mary I; even so two radicals were executed in Edward's reign (one for denying the reality of the incarnation, the other for denying Christ's divinity). Under Mary, around two hundred and ninety people were burned at the stake between 1555 and 1558 after the restoration of papal jurisdiction. When Elizabeth I came to the throne, the concept of heresy was retained in theory but severely restricted by the 1559 Act of Supremacy and the one hundred and eighty or so Catholics who were executed in the forty-five years of her reign were put to death because they were considered members of "...a subversive fifth column." The last execution of a "heretic" in England occurred under James VI and I in 1612. Although the charge was technically one of "blasphemy" there was one later execution in Scotland (still at that date an entirely independent kingdom) when in 1697 Thomas Aikenhead was accused, among other things, of denying the doctrine of the Trinity.
