Para-jumble (sentence arrangement): Arrange P–Q–R–S to complete the reflection on growing up, human reasoning, and responsible actions. S1 = "Growing up means not only getting larger, but also using our senses and our brains to become more aware of the world around us." Q = "In this, humans differ from all other animals." P = "Not only do we have memory, but we are able to think and reason." S = "This means we can plan what we are going to do—using prior experience—before we do it." R = "Before we spray roadside plants or turn sewage into our rivers, we should pause to think about the likely results of our actions." S6 = "In other words, we must develop and use our ability to reason because the destruction or preservation of our environment depends on us." Between S1 and S6, place P–Q–R–S in a logically developing order. Choose the correct sequence of P–Q–R–S that completes the paragraph.
