It is a situation where I am trying to promote a new type low-fat snack food to a group of people in the grocery store.
I learned from their behavior that they are paying attention and are trying to process my message.
Thus I will provide useful information about the low-fat snack food. I will also try to make them understand the health benefits that these low fat food offers. I will also aware these people about the ill effects of high fat food to our health. In short I will convey strong messages with several high-quality arguments to the people in the store.
Thus the answer is "a message with several high-quality arguments."
I believe the answer is Transpiration. Transpiration refers to the process of water movement through the plant and aerial surrounding the plant The transpiration in plants happen due to the plants effort to transfer necessary substance/nutrients that needed by all part of its body.
