1. Our perception is not perfect and can lead us to see illusions —— for example, reversing the arrow-like angles on one of two lines of equal length makes them look different lengths.
2. Our everyday lives are full of assumptions, but we can find a number of possible solutions to problems we are facing if we reverse our ideas and challenge assumptions.
3. Assumptions that are taken for granted in our lives are based on the long history of human experiences and wisdom, but history itself does not always lead us to the right answer.
4. Assumptions can hinder creative ways of solving problems, so when you hire a new employee, you should check that the applicant does not hold too many assumptions.

Fill in the blanks, thinking back to the answer to the question following each section numbers. Read the finished summary aloud.

Reversing ①（our conventional thinking patterns） about problems and situations will change our perception and enable us to achieve our goals. If we start with incorrect assumptions when trying to solve problems, the solutions ②（will be poorly constructed）. However, we never think of challenging basic and fundamental assumptions. At times, we mistake the false face which an assumption presents to us ③（for something immutable）. Problems often come with assumptions, and these assumptions may ④（hinder creativity）, shutting out other possibilities. We need to realize that nothing is sacrosanct and challenge assumptions to open the path to ⑤（all sorts of discoveries）.
