Input: Article: The new peace would only last for two years; war recommenced in the aftermath of John's decision in August 1200 to marry Isabella of Angouleme. In order to remarry, John first needed to abandon Isabel, Countess of Gloucester, his first wife; John accomplished this by arguing that he had failed to get the necessary papal permission to marry Isabel in the first place as a cousin, John could not have legally wed her without this. It remains unclear why John chose to marry Isabella of Angouleme. Contemporary chroniclers argued that John had fallen deeply in love with Isabella, and John may have been motivated by desire for an apparently beautiful, if rather young, girl. On the other hand, the Angoumois lands that came with Isabella were strategically vital to John: by marrying Isabella, John was acquiring a key land route between Poitou and Gascony, which significantly strengthened his grip on Aquitaine.[nb 5]

Now answer this question: When was John's decision to marry Isabella?

Output: August 1200

Input: Article: Black people is a term used in certain countries, often in socially based systems of racial classification or of ethnicity, to describe persons who are perceived to be dark-skinned compared to other given populations. As such, the meaning of the expression varies widely both between and within societies, and depends significantly on context. For many other individuals, communities and countries, "black" is also perceived as a derogatory, outdated, reductive or otherwise unrepresentative label, and as a result is neither used nor defined.

Now answer this question: Can the term "black people" have different meanings?

Output:
the meaning of the expression varies widely both between and within societies, and depends significantly on context.
