The teacher may find other words the students use frequently with the word "that", and can help the students find new appropriate expressions. III. The teacher may decide to study the issue further, and test individual paragraphs in the students' works, or may decided to test all of their essays in one word cloud.

Consider an algorithm that simulates rolling two number cubes, Cube1 and Cube2, with the numbers 1-6, and then displays the sum of the cubes' values. If the sum is greater than 10, "Winner!" is also displayed; otherwise, "Loser" is displayed. Put the steps of the algorithm in order. Select two answers. Step 1: Assign random values between 1 and 6 to Cube1. Step 2: If sum is greater than 10, display "Winner". Step 3: Display Sum. Step 4: If the sum is less than or equal to 10, display "Loser". Step 5: Assign random values between 1 and 6 to Cube2. Step 6: Assign the value of Cube1 + Cube2 to sum
