[Q]: Question: "Lignin makes up 15-30% of what structure?" Context: "Wood is a heterogeneous, hygroscopic, cellular and anisotropic material. It consists of cells, and the cell walls are composed of micro-fibrils of cellulose (40% 50%) and hemicellulose (15% 25%) impregnated with lignin (15% 30%)." Answer:
****
[A]: cell walls

input: Please answer the following: Question: "What led to free tolls?" Context: "The development of the Bronx is directly connected to its strategic location between New England and New York (Manhattan). Control over the bridges across the Harlem River plagued the period of British colonial rule. Kingsbridge, built in 1693 where Broadway reached the Spuyten Duyvil Creek, was a possession of Frederick Philipse, lord of Philipse Manor. The tolls were resented by local farmers on both sides of the creek. In 1759, the farmers led by Jacobus Dyckman and Benjamin Palmer built a "free bridge" across the Harlem River which led to the abandonment of tolls altogether." Answer:
++++++++++
output: farmers led by Jacobus Dyckman and Benjamin Palmer built a "free bridge"

Please answer this: Question: "What is the length of one side of an individual aerobic gymnasts performance area?" Context: "Aerobic gymnastics (formally Sport Aerobics) involves the performance of routines by individuals, pairs, trios or groups up to 6 people, emphasizing strength, flexibility, and aerobic fitness rather than acrobatic or balance skills. Routines are performed for all individuals on a 7x7m floor and also for 1214 and 15-17 trios and mixed pairs. From 2009, all senior trios and mixed pairs were required to be on the larger floor (10x10m), all groups also perform on this floor. Routines generally last 6090 seconds depending on age of participant and routine category." Answer:
++++++++
Answer: 7x7m

Problem: Question: "What can seem to be pointless?" Context: "Whereas the chromosomes of prokaryotes are relatively gene-dense, those of eukaryotes often contain regions of DNA that serve no obvious function. Simple single-celled eukaryotes have relatively small amounts of such DNA, whereas the genomes of complex multicellular organisms, including humans, contain an absolute majority of DNA without an identified function. This DNA has often been referred to as "junk DNA". However, more recent analyses suggest that, although protein-coding DNA makes up barely 2% of the human genome, about 80% of the bases in the genome may be expressed, so the term "junk DNA" may be a misnomer." Answer:

A: eukaryotes

Problem: Given the question: Question: "What quantity of groups have relationships that can't be narrowed down?" Context: "The exact relationship between these eight groups is not yet clear, although there is agreement that the first three groups to diverge from the ancestral angiosperm were Amborellales, Nymphaeales, and Austrobaileyales. The term basal angiosperms refers to these three groups. Among the rest, the relationship between the three broadest of these groups (magnoliids, monocots, and eudicots) remains unclear. Some analyses make the magnoliids the first to diverge, others the monocots. Ceratophyllum seems to group with the eudicots rather than with the monocots." Answer:
++++++++++++++++++++++++++++++++
The answer is:
three

Problem: Question: "Were there more civilians or law enforcement officers killed in the attacks?" Context: "The city and surrounding area suffered the bulk of the economic damage and largest loss of human life in the aftermath of the September 11, 2001 attacks when 10 of the 19 terrorists associated with Al-Qaeda piloted American Airlines Flight 11 into the North Tower of the World Trade Center and United Airlines Flight 175 into the South Tower of the World Trade Center, and later destroyed them, killing 2,192 civilians, 343 firefighters, and 71 law enforcement officers who were in the towers and in the surrounding area. The rebuilding of the area, has created a new One World Trade Center, and a 9/11 memorial and museum along with other new buildings and infrastructure. The World Trade Center PATH station, which opened on July 19, 1909 as the Hudson Terminal, was also destroyed in the attack. A temporary station was built and opened on November 23, 2003. A permanent station, the World Trade Center Transportation Hub, is currently under construction. The new One World Trade Center is the tallest skyscraper in the Western Hemisphere and the fourth-tallest building in the world by pinnacle height, with its spire reaching a symbolic 1,776 feet (541.3 m) in reference to the year of American independence." Answer:

A:
civilians
