Please choose the correct ending to complete the given sentence: Computers and Electronics: [header] How to cook long grained rice [title] Measure out the desired quantity of rice. [step] Long grain rice will expand to triple its size during cooking, so take this into account when deciding how much to make. [title] Rinse the rice (optional).

Ending1: [step] Adding cold water to the rice and draining it will remove loose starches without losing nutrients. This may result in fluffier rice, although some milling processes leave little excess starch to remove. Ending2: [step] Rinse the rice by running water over the area where you will cook it. Any leftover water also helps to dry the rice faster. Ending3: [step] If your rice is already slightly soiled or has been dried out during cooking, you will need to rinse it with clean water. [substeps] This cannot be done while the rice is still raw, because some parts of the rice's material, such as flour and rice starch, can only be removed with water. Ending4: [step] This is a good way to give the long grain rice a definitive scent and check for any absence of flavor. Rinsing the rice prevents moisture from building up in the rice while it cooks.
