(d) Disproportionate Growth
Globalisation has led to uneven benefits — while the wealthy and skilled have gained, many small producers and workers have suffered, causing disproportionate growth.
The other three options (access to new markets, new talent, international recruitment) are benefits of globalisation, not challenges. Disproportionate growth is a challenge because globalisation has not been uniform in its impact — it has widened inequality between rich and poor, and between developed and developing countries. The passage clearly states that "not everyone has benefited from globalisation." Examiners expect students to distinguish between benefits and challenges of globalisation.
