Final answer:
Leila is using the strategy of drawing inferences by logically assuming that the exploding drink described was a carbonated beverage based on the characteristics of CO2 under pressure in a contained environment.
Step-by-step explanation:
The strategy that Leila is using by concluding that the drink must have been a carbonated beverage is called drawing inferences. An inference is a conclusion reached by applying logic to the evidence provided. In this case, the evidence is an exploding drink when opened, which Leila logically associates with the characteristics of carbonated beverages because when a container of such a beverage is not carefully opened, the pressure change can cause the CO2 to come out of solution suddenly, leading to an explosion of fizz.
