UPSC 2014: In India, cluster bean (Guar) is traditionally used as a vegetable or animal feed, but recently the cultivation of this has assumed significance. Which one of the following statements is correct in this context?
(a)The oil extracted from seeds is used in the manufacture of biodegradable plastics
(b)The gum made from its seeds is used in the extraction of shale gas
(c)The leaf extract of this plant has the properties of anti-histamines
(d)It is a source of high quality biodiesel
Attempt This Question
Not attemptedCorrect Answer: (b) The gum made from its seeds is used in the extraction of shale gas
Guar seeds yield guar-gum, a polysaccharide that is added to hydraulic-fracturing fluids to increase their viscosity; this makes it valuable for shale-gas extraction, hence option (b) is right. The oil of guar is not used for bioplastics, its leaves have no recognized antihistamine property, and the plant is not a biodiesel feed-stock, so options (a), (c) and (d) are incorrect.
