Final answer:
The answer to the crystal-eating dilemma is (D) Not enough information, as there is no data given to resolve which apprentice ate which crystal. For observing planets, various resources such as online planetariums, apps, local astronomy clubs, or library resources could be used to determine visible planets. The historical note on digestion exemplifies how unintended circumstances can advance scientific knowledge.
Step-by-step explanation:
To answer the question of determining who ate which crystal, based on the information provided, the answer would be (D) Not enough information. Without additional clues or details about the apprentices, the crystals, or the circumstances under which each crystal was swallowed, it is impossible to accurately determine which apprentice ate which crystal. This question seems like a logic puzzle and would typically require more information to solve.
To find out which planets are currently visible in the sky during the evening and morning, several resources could be used. These include online planetarium websites, astronomy apps, or a visit to the local library to consult astronomy books or almanacs that list planetary positions. Additionally, contacting a local astronomy club or observatory can provide valuable information. If internet access is available, websites such as NASA's website or astronomy forums can offer up-to-date information about planetary visibility.
The historical note about digestion and the doctor treating the fur trapper is fascinating but not directly related to the question at hand. It illustrates the incremental progress of medical knowledge, and in this case, how a catastrophic injury led to a significant scientific observation that contributed to the understanding of the digestive process.
