Criteria Feedback
- The student communicates the biological topic clearly and keeps the investigation tightly centered on carbapenem resistance in P. aeruginosa.
- The student's research question is focused and specific, which gives the essay a strong analytical direction.
- The student explains the chosen secondary-data approach clearly and shows awareness of why the selected studies are relevant.
- The operational meaning of “to what extent” is not defined clearly enough.
- The student's methodological justification would be stronger with a more explicit search and selection strategy.
- The evidence base is somewhat narrow, so the connection between the question and the data is not as direct as it could be.

B.1Application of source material
Good
B.2Use of terminology and concepts
Moderate
Criteria Feedback
- The student uses source material that is broadly relevant to the topic and connects it purposefully to the resistance mechanism under discussion.
- The student's biological terminology is mostly accurate and helps build a coherent explanation.
- The student shows a solid understanding of how efflux pumps can reduce intracellular antibiotic concentration.
- Some of the source use is indirect, especially where proxy data are used to support claims about carbapenem resistance.
- A few terminology and concept errors weaken precision, especially around MIC and the direction of transport.
- Some biological claims are stated too absolutely when the underlying evidence is more cautious.
