Problem: Given the question: Extract the answer to the question from the following context. Question: What fuels muscle movement in the digestive system? Context: Underlying the process is muscle movement throughout the system through swallowing and peristalsis. Each step in digestion requires energy, and thus imposes an "overhead charge" on the energy made available from absorbed substances. Differences in that overhead cost are important influences on lifestyle, behavior, and even physical structures. Examples may be seen in humans, who differ considerably from other hominids (lack of hair, smaller jaws and musculature, different dentition, length of intestines, cooking, etc.).

Problem: Given the question: Extract the answer to the question from the following context. Question: What is an Entered Apprentice? Context: The bulk of Masonic ritual consists of degree ceremonies. Candidates for Freemasonry are progressively initiated into Freemasonry, first in the degree of Entered Apprentice. Some time later, in a separate ceremony, they will be passed to the degree of Fellowcraft, and finally they will be raised to the degree of Master Mason. In all of these ceremonies, the candidate is entrusted with passwords, signs and grips peculiar to his new rank. Another ceremony is the annual installation of the Master and officers of the Lodge. In some jurisdictions Installed Master is valued as a separate rank, with its own secrets to distinguish its members. In other jurisdictions, the grade is not recognised, and no inner ceremony conveys new secrets during the installation of a new Master of the Lodge.
