Question of the Day (13-Apr-19)
A decline in pollinating insects in India is resulting in reduced vegetable yields and could limit people's access to a nutritional diet, a study warns. Indian researchers said there was a "clear indication" that pollinator abundance was linked to productivity. They added that the loss of the natural service could have a long-term impact on the farming sector, which accounts for almost a fifth of the nation's GDP. The ideal situation would have been if we were able to compare the overall pollinator abundance over the years, but that kind of data was just not available.
Which of the following, if true, would most strengthen the study in the absence of data about pollinator abundance?
| ||1)||Data shows that in ecological farming, which is a hybrid of conventional and organic farming, there is pollinator abundance.|
| ||2)||Certain vegetables, like tomato, did not depend on insects for pollination but relied on other mechanisms, such as the wind, to carry the pollen.|
| ||3)||Data shows that the yields of pollinator-independent crops have continued to increase while pollinator-dependent crops have decreased.|
| ||4)||Many vegetables - such as pumpkin, squash, cucumber and gherkins - were reliant on insects, such as bees, for pollination.|
| ||5)||Data shows that the yields of pollinator-dependent crops have continued to increase while pollinator-independent crops have decreased.|
