HOTSPOT
You have a basket of eight apples.
You want to give one of the apples to your best friend Jo Berry. You decide to pick the one that weighs the most.
You need to analyze the following methods and determine whether that method can be used to consistently achieve your goal.
Method 1:
For each apple, measure its weight using a scale. Write down the weight on a sticky note. Put the sticky note on the apple. Ensure that the same unit of measure (e g. ounce, gram, or kilogram) is consistently used. Once all apples have been measured, find the apple with the largest number on its sticky note.
Method 2:
Divide the apples into two lots. Each lot should have four apples. Compare the weight of the two lots using a balance scale. Put the lighter lot aside. Divide the remaining apples into two lots of two apples. Compare the weight of the two lots using a balance scale. Put the lighter lot aside. Compare the weight of the two remaining apples. The heavier apple is the one that weighs the most.
Method 3:
Take two apples from the basket. Use a balance scale to compare them. Keep replacing the lighter apple on the balance scale with another apple from the basket until the basket is empty. The heavier apple remaining on the scale is the one that weighs the most.
For each of the methods, select Yes if the method can consistently achieve your goal. Otherwise, select No.
NOTE: Each correct selection is worth one point.
