Question: Many hunter-gatherers consciously manipulate the landscape through cutting or burning undesirable plants while encouraging desirable ones, some even going to the extent of slash-and-burn to create habitat for game animals. These activities are on an entirely different scale to those associated with agriculture, but they are nevertheless domestication on some level. Today, almost all hunter-gatherers depend to some extent upon domesticated food sources either produced part-time or traded for products acquired in the wild.
Try to answer this question if possible: Which group burns desirable plants while encouraging undesirable ones?
Answer: unanswerable

Question: During her childhood, Madonna was inspired by actors, later saying, "I loved Carole Lombard and Judy Holliday and Marilyn Monroe. They were all incredibly funny ... and I saw myself in them ... my girlishness, my knowingness and my innocence." Her "Material Girl" music video recreated Monroe's look in the song "Diamonds Are a Girl's Best Friend", from the film Gentlemen Prefer Blondes (1953). She studied the screwball comedies of the 1930s, particularly those of Lombard, in preparation for the film Who's That Girl. The video for "Express Yourself" (1989) was inspired by Fritz Lang's silent film Metropolis (1927). The video for "Vogue" recreated the style of Hollywood glamour photographs, in particular those by Horst P. Horst, and imitated the poses of Marlene Dietrich, Carole Lombard, and Rita Hayworth, while the lyrics referred to many of the stars who had inspired her, including Bette Davis, described by Madonna as an idol. However, Madonna's film career has been largely received negatively by the film critic community. Stephanie Zacharek, critic for Time magazine, stated that, "[Madonna] seems wooden and unnatural as an actress, and it's tough to watch, because she's clearly trying her damnedest." According to biographer Andrew Morton, "Madonna puts a brave face on the criticism, but privately she is deeply hurt." After the box office bomb Swept Away (2002), Madonna vowed that she would never again act in a film, hoping her repertoire as a bad actress would never be discussed again.

Question: Hops contain several characteristics that brewers desire in beer. Hops contribute a bitterness that balances the sweetness of the malt; the bitterness of beers is measured on the International Bitterness Units scale. Hops contribute floral, citrus, and herbal aromas and flavours to beer. Hops have an antibiotic effect that favours the activity of brewer's yeast over less desirable microorganisms and aids in "head retention", the length of time that a foamy head created by carbonation will last. The acidity of hops is a preservative.
Try to answer this question if possible: What do you call the length of time that foam is on top of beer because of carbonation?
Answer:
head retention
