Reading the passage
The last sentence says continued success could help overcome environmental chemistry's reputation for ineffectiveness and high cost. What would make that hopeful assessment concrete? We already have useful applications; cheaper production could make the material practical in a much larger market.
What we’re looking for
A strong scenario would connect the company's present niche successes to an ability to produce polyaspartate affordably and at scale.
Working the answers
- A
A marketing video could publicize effectiveness, but it doesn't lower the price that drove companies away. The main obstacle wasn't a failure to show that the material could control scale.
- B
Competitors developing alternatives to polyaspartate might make the market more active. But that doesn't show Koskan's own product continuing to succeed or overcoming its expense. The final sentence ties the broader hope to his company's success.
- CCorrect
Sales to the oil and farming industries fund low-cost, large-volume production. That supplies the missing bridge: successful specialized applications generate the resources to address the cost barrier, allowing general use. It shows how the early successes could become something much larger.
- D
The buildup of polyacrylates in landfills is already the problem motivating interest in a replacement. More evidence of that problem doesn't show that polyaspartate has become an affordable, effective solution.
- E
Difficulty isolating the useful form creates another production obstacle. It doesn't demonstrate the continued commercial success envisioned in the final sentence.
