The validity characteristic of a written test would be most enhanced if every student were equally adept at test-taking skills.
Describes five types of test items: Multiple Choice, True/False, Matching, Completion, and Essay. This information includes proper usage of each article type, strengths and weaknesses of each article type, and characteristics of well-written articles.
The written exam primarily serves to assess knowledge-based learning outcomes. But you can also test-taking skills and attitude. These are part of the student's overall assessment plan. Test questions are open-ended and must be answered in the form of an essay or short statement in your own words.

Answer:
Explanation:
lithosphere
Earth's crust, called the lithosphere, consists of 15 to 20 moving tectonic plates. The plates can be thought of like pieces of a cracked shell that rest on the hot, molten rock of Earth's mantle and fit snugly against one another.
The Louisiana Purchase is important because it gave the U.S. control of the Mississippi River and the port city of New Orleans, both of which were used by farmers to ship their crops and get paid.
The first description of the DNA (deoxyribonucleic acid)chain was done by Watson and Crick in 1953, the nucleotides that constitute the DNA are four: cytosine (C), guanine (G), timine (T) and adenine (A). When doing a model is essential to remember that cytosine ONLY joins guanine and timine only link adenine, this is due to the size and chemical properties of each molecule. Later, another related and similar and molecule was discovered, the ribonucleic acid or RNA, which also is constructed by nucleotides.
In both cases, the nucleotides are compound of 3 main components: a nitrogen base, a pentose and a phosphate. When the molecule lacks the phosphate group, is called nucleoside. Depending on the chain ( DNA or RNA) the nitrogen base derives from purine (adenine and guanine) or pyrimidine (cytosine or timine) just in the RNA instead of timine is uracil (U)
The union is established between adjacent molecules through the phosphate, while among each other through the nitrogen base-remember C=G and T or U=A. The core of each molecule is the pentose. Therefore the best representation of the molecule is attached

Answer:
The eight-year Japanese invasion caused tremendous damage to China in terms of civilian and military casualties and property losses. More importantly, even seven decades after the end of the war, the two countries have not reached any reconciliation.The United States responded to this growing threat by temporarily halting negotiations with Japanese diplomats, instituting a full embargo on exports to Japan, freezing Japanese assets in U.S. banks, and sending supplies into China along the Burma Road.
