Teacher:In this task, you are given a context and four options. Each option is a suggested ending for the context. You should read the context and pick the best ending for the context. Please answer with "A", "B", "C", and "D".
Teacher: Now, understand the problem? Solve this instance: [header] How to build a calorimeter [title] Get a small metal can. [step] This can will be used to contain water that will be heated as part of the calorimetric measurements. Any small metal can will work, such as those used to package vegetables, or a soda can. <sep> (A) Or, any small ceramic or glass container will do. Stick a penny or coin in the minnow to hold its weight. (B) [title] Gather the bottles for the calorimeter. [step] You can buy bottles in a larger size, or leave them in a smaller size while constructing the calorimeter. (C) Set the can on a table to catch any spills while you design the calorimeter. [substeps] Make sure that your can is at least 16 inches (45.7 cm) from the heat source. (D) Make sure that it is empty, clean, and open on one end. If you are using a soda can, the opening used for drinking out of the can will suffice.
