Directions: In the following passage, for each numbered blank, five words/phrases are suggested, one of which best fits the blank appropriately.

Can an experiment conceived, carried out, and reported in kids-speak with pencil-coloured figures and hand-written tables by school children aged 8 to 10 years get published in a highly rated international journal following a peer-reviewing process? Twenty-seven schoolchildren from a primary school in UK have proved this is possible if a simple but novel scientific question raised is __(i)__ in a scientific way. Their paper was published in the Royal Society's Biology Letters journal. Their __(ii)__ was that bumble-bees can use a combination of colour and spatial relationships in deciding which colour of flower to forage from. Considering that our understanding of how bees perceive coloured patterns and scenes is inadequate, this inspiring outcome has shown that schoolchildren guided by gifted teachers can think and carry out experiments like any hard-wired scientist. For these kids, doing science changed their __(iii)__ of the subject. Science also became cool and fun. This refreshing approach turns the spotlight on the best methods of teaching science. The __(iv)__ learning system adopted by most schools in India, even classroom study combined with some laboratory work with pre-defined outcomes, does very little to __(v)__ curiosity and interest in science. Is that one of the reasons why out-of-the-box thinking that produces path-breaking science rarely comes out of Indian laboratories? The children at the UK school had their gifted teacher to guide them. Scientists from India's space and atomic energy departments and in some other places where serious science is done can take a leaf out of the school's book and lead the way in engaging with school pupils and getting them to do real science.
