Listen to the lesson carefully, then answer 10 comprehension questions. Pick one option per question.

Question 1What is the main topic of the supervision meeting?

How graphene was first isolated in the laboratory Why graphene's commercial promise remains largely unrealised How to design flexible phone screens for sale Which postgraduate students deserve research funding

Question 2What most worried potential industrial partners about graphene?

The poor performance of the material The high price of laboratory equipment The consistency of the supply The lack of academic publications

Question 3What happened to the students' revised deadline for the literature review?

It moved from June to October It stayed fixed in early June It moved forward to March It was cancelled by Professor Lane

Question 4In which year was graphene first isolated, according to the professor?

In nineteen ninety four In two thousand fourteen In the late nineteen eighties In two thousand four

Question 5What is the core difficulty in commercialising graphene?

Manufacturing large defect free sheets at affordable cost Convincing the public that the material is safe Finding enough carbon to meet global demand Training engineers to handle the material

Question 6What did the professor note about the flexible phone screen prototypes?

They were too expensive to mass produce They repeatedly failed durability testing They attracted no interest from manufacturers They performed far better than expected

Question 7What stalled progress on the water filtration membranes?

A shortage of raw materials Disagreements between research teams Certification delays Poor results in field trials

Question 8What did Professor Lane advise the students to do in their review?

Focus only on laboratory results Remove the section on phone screens Add more historical background detail Compare graphene with competing materials

Question 9What was wrong with the first draft of the literature review?

It was written in a celebratory tone It ignored the history of graphene It contained too many technical errors It was far shorter than required

Question 10What did the students accept had driven most early expectations?

Solid experimental evidence Pressure from industrial partners Advice from their supervisor Hype rather than science
