Read the following passage and answer the items that follow. Your answer to these items should be based on the passages only

For generations, companies have been selling fair skin to young Indian women, promising better marriage and employment prospects. However, over the last few years, men have become a favoured target audience. This followed the realisation that the Indian alpha male, denied a choice in male-specific grooming products, had been using women’s fairness creams all along. Until the mid-2000s, deodorants and shaving creams were the only grooming products advertised for men. But India’s largest consumer goods companies sensed an opportunity, and launched a slew of fairness products for male consumers.

In India, as in other parts of the world, light skin is the culturally accepted and endorsed form of beauty, and children absorb this message at a young age. According to a 2015 research report by Nielsen, urban Indian men believe that fair skin can improve professional prospects. The cultural pressure to look fair, argues Kiran Khalap, branding expert and founder at communications consultancy Chlorophyll, is something inherent in our society, not manufactured by companies. “And it is certainly not restricted to India: China and Japan have had skin-whitening products for centuries, well before they met Western ‘white’ people,” he said. However, there is a growing awareness among consumers that companies are exploiting their insecurities, and critics have taken some of the biggest fairness brands, and the celebrities who endorse them, to task for their casual discrimination.

Earlier this month, the “Dark is Beautiful” campaign was launched to encourage Indians to embrace a wider definition of beauty. These efforts are slowly making a difference, increasing awareness and encouraging consumers to take pride in their natural skin tones. That means Indian companies will eventually have to change their approach. “My sense is that brands will wake up to the new reality, and you will see propositions reworked around clearer skin (and) glow, rather than pure fairness,” Leo Burnett’s spokesman said.
