The first characteristic is also the most complex: composition. The composition usually involves smaller geometric
shapes that are repeated, creating rhythm. A grid of either equilateral triangles or squares is used as a foundation, but
sometimes a twist on the triangle grid-a hexagonal grid-is used instead. Circles, squares, and straight lines provide the
basis for the pattern, which is interlaced, combined, and duplicated in order to create a beautiful design. In mathematics,
these grids of repeated figures are called tessellations, a word which is derived from the Latin word tessere, meaning
“pieces of mosaic." A tessellation repeats a polygon over and over to tile a plane.
To boost fluency, which words should be practiced ?
a equilateral
C. tessere
b. tessellations
d. all of the above

Which excerpt from tinker v. des moines shows how precedent support an argument? a. "as we shall discuss, the wearing of armbands in the circumstances of this case was entirely divorced from actually or potentially disruptive conduct by those participating in it. it was closely akin to 'pure speech' which, we have repeatedly held, is entitled to comprehensive protection under the first amendment. cf. cox v. louisiana, 379 u.s. 536, 555 (1965); adderley v. florida, 385 u.s. 39 (1966)." b. "while the absence of obscene remarks or boisterous and loud disorder perhaps justifies the court's statement that the few armband students did not actually 'disrupt' the classwork, i think the record overwhelmingly shows that the armbands did exactly what the elected school officials and principals foresaw they would." c. "i, for one, am not fully persuaded that school pupils are wise enough, even with this court's expert from washington, to run the 23,390 public school systems [n4] in our 50 states." d. "under our constitution, free speech is not a right that is given only to be so circumscribed that it exists in principle, but not in fact. freedom of expression would not truly exist if the right could be exercised only in an area that a benevolent government has provided as a safe haven for crackpots."

The greatest gift the sumerians gave the world was the invention of writing. the sumerians were wealthy people. they needed some way to keep track of what they owned. they began drawing pictures. they used a reed as a pen. they drew on soft pieces of clay. the soft clay was then dried in the sun. the tablet became a permanent record. later, the sumerian drawings changed into wedge-shaped symbols. this kind of writing is called cuneiform. by putting symbols together, the sumerians could write entire sentences.
