Answer: Two sentences that show sequential organization are:
* The recipe said that I had to spread the tomato sauce onto the crust first, and, then, put cheese onto it.
* The user manual said that I had to install the SIM card before charging the battery of my phone.
Explanation: A piece of writing can be organized following different organizational patterns. One of them is sequential oganization, which consists in presenting steps of a process in the order in which they must be followed. Therefore, this type of organization is found in texts such as user manuals or recipes. For example, in the sentences provided, there are steps that come before others; therefore, information has been organized in terms of a sequence. The words that indicate sequence are "first", "then" and "before".
