Question: Aside from water, wood has three main components. Cellulose, a crystalline polymer derived from glucose, constitutes about 4143%. Next in abundance is hemicellulose, which is around 20% in deciduous trees but near 30% in conifers. It is mainly five-carbon sugars that are linked in an irregular manner, in contrast to the cellulose. Lignin is the third component at around 27% in coniferous wood vs. 23% in deciduous trees. Lignin confers the hydrophobic properties reflecting the fact that it is based on aromatic rings. These three components are interwoven, and direct covalent linkages exist between the lignin and the hemicellulose. A major focus of the paper industry is the separation of the lignin from the cellulose, from which paper is made.
Try to answer this question if possible: What kind of trees have about 30% hemicellulose?
Answer: conifers
Question: One use of the term "computer security" refers to technology that is used to implement secure operating systems. In the 1980s the United States Department of Defense (DoD) used the "Orange Book" standards, but the current international standard ISO/IEC 15408, "Common Criteria" defines a number of progressively more stringent Evaluation Assurance Levels. Many common operating systems meet the EAL4 standard of being "Methodically Designed, Tested and Reviewed", but the formal verification required for the highest levels means that they are uncommon. An example of an EAL6 ("Semiformally Verified Design and Tested") system is Integrity-178B, which is used in the Airbus A380 and several military jets.

Question: This format often includes dance-pop (such as upbeat songs by Madonna, Cher, Gloria Estefan and Kylie Minogue), power pops (mainly by boybands such as Backstreet Boys and Westlife), and adult-oriented soft rock music that are ballad-driven (typically by Aerosmith[citation needed], The Eagles, Sting, Toto and The Moody Blues). Generally, Hot AC radio stations target their music output towards the 18-54 age group and a demographic audience of both men and women.
Try to answer this question if possible: Madonna, Cher, Gloria Estefan and Kylie Minogue are artists in what genre of music?
Answer: dance-pop
Question: The field of neuroscience encompasses all approaches that seek to understand the brain and the rest of the nervous system. Psychology seeks to understand mind and behavior, and neurology is the medical discipline that diagnoses and treats diseases of the nervous system. The brain is also the most important organ studied in psychiatry, the branch of medicine that works to study, prevent, and treat mental disorders. Cognitive science seeks to unify neuroscience and psychology with other fields that concern themselves with the brain, such as computer science (artificial intelligence and similar fields) and philosophy.
Try to answer this question if possible: What field of science studies the brain and the central nervous system?
Answer:
neuroscience
