 Today, most scientists and almost all countries use the International System of Units. One advantage of using SI measurements is that they help all scientists share and compare their observations and results. Another advantage of SI is that all units are based on the number of 10. This makes changing from one unit to another easier.  Based on the information in this passage, the reader can conclude that SI helps ◦ A. scientists from different countries work together ◦ B. scientists understand past events ◦ C. people understand scientific methods ◦ D. scientists make models

 There is a difference between an expository summary and a narrative summary. On your paper, explain the difference between these in your own words.

 Expository Summary: includes the main idea and the most important details  Narrative Summary: is a plot summary, should include a part from the beginning, the middle, and the end -BME-

 Plasma is the state of matter that does not have a definite shape or volume and whose particles have broken apart. Plasmas have some properties that are quite different from the properties of gases. Plasmas conduct electric current, while gases do not. Electric and magnetic fields affect plasmas but do not affect gases. In fact, strong magnetic fields are used to hold very hot plasmas that would destroy any other container.  The author helps readers understand the main idea of the passage by ◦ A. comparing the properties of plasmas and gases ◦ B. listing the properties of gases ◦ C. summarizing the properties of all kinds of matter ◦ D. arranging the information in order of importance *Hint: Find the main idea first in order to answer this question successfully.
