In this exercise, it is important to choose the correct meaning or color, depending on what is asked.
By meaning, you need to select the symbol of the form that is asked.
By color, you have to select the color of the text. For instance, if you read "Green", but the color of the letters are red, select a red symbol.
With higher levels of difficulties, you will find an equal sign that is crossed out. In that case, all results are correct that are not equal to the asked symbol or color.
