Final answer:
Lorna would be considered an Enthusiastic learner, reflecting her passion for chemistry and her desire to share this passion with others.
Step-by-step explanation:
Lorna loves chemistry and enjoys sharing her knowledge with others. Based on this description, Lorna would be considered an Enthusiastic learner. This term describes someone who is passionate about a subject and is eager to learn more as well as to help others understand it. It does not necessarily imply that she is exclusively focused on her studies like a bookworm, seeking approval like a teacher's pet, or limited to stereotypically nerdy pursuits. Instead, it reflects a broad and active engagement with the subject matter, much like the dedicated professionals such as Dr. Deanna D'Alessandro, who lovingly pursues chemistry not only as a career but as a calling to discover and educate.
