Problem: Please answer a question about the following article about Samurai:
A samurai could divorce his wife for a variety of reasons with approval from a superior, but divorce was, while not entirely nonexistent, a rare event. A wife's failure to produce a son was cause for divorce, but adoption of a male heir was considered an acceptable alternative to divorce. A samurai could divorce for personal reasons, even if he simply did not like his wife, but this was generally avoided as it would embarrass the person who had arranged the marriage. A woman could also arrange a divorce, although it would generally take the form of the samurai divorcing her. After a divorce samurai had to return the betrothal money, which often prevented divorces.
What could samurai do instead of divorce if their wife couldn't produce a son?
A: adoption of a male heir

Noteworthy Irish mandolinists include Andy Irvine (who, like Johnny Moynihan, almost always tunes the top E down to D, to achieve an open tuning of GDAD), Paul Brady, Mick Moloney, Paul Kelly and Claudine Langille. John Sheahan and the late Barney McKenna, respectively fiddle player and tenor banjo player with The Dubliners, are also accomplished Irish mandolin players. The instruments used are either flat-backed, oval hole examples as described above (made by UK luthier Roger Bucknall of Fylde Guitars), or carved-top, oval hole instruments with arched back (made by Stefan Sobell in Northumberland). The Irish guitarist Rory Gallagher often played the mandolin on stage, and he most famously used it in the song "Going To My Hometown."

What Irish guitarist played the mandolin on stage?
Answer: Rory Gallagher

Input: Wood
Little is known about the bacteria that degrade cellulose. Symbiotic bacteria in Xylophaga may play a role in the degradation of sunken wood; while bacteria such as Alphaproteobacteria, Flavobacteria, Actinobacteria, Clostridia, and Bacteroidetes have been detected in wood submerged over a year.

What component of wood is degraded by bacteria that scientists are still trying to learn about?
Output: cellulose


Problem: Please answer a question about the following article about Animal:
A zygote initially develops into a hollow sphere, called a blastula, which undergoes rearrangement and differentiation. In sponges, blastula larvae swim to a new location and develop into a new sponge. In most other groups, the blastula undergoes more complicated rearrangement. It first invaginates to form a gastrula with a digestive chamber, and two separate germ layers — an external ectoderm and an internal endoderm. In most cases, a mesoderm also develops between them. These germ layers then differentiate to form tissues and organs.
What may be formed between the external ectoderm and an internal endoderm layers?
A:
mesoderm
