I'm working on my resume post graduate school (master's) and am having trouble deciding how to list assistantships. While in school I was a GRA under two different grants which funded entities withing the university(doing very different things) and a TA for on semester. I'm planning on listing these under work experience but should they each be listed as a unique experience (option 1) or should all the positions be listed as one entry (option 2). The obvious pros/cons are option 1 allows me to showcase a larger diversity of experiences and skills but takes up quite a bit of space option 2 is the opposite. Below is an example
Option 1
Entity XYZ
Research Assistant

Entity ABC
Research Assistant
- Description
Department MNO
Teaching Assistant

Option 2
