Hello Aspirants.

Welcome to Online English Section with explanation in Affairs Here we are creating question sample in Cloze test, which is BASED ON IBPS PO/CLERK/LIC AAO/RRB & SSC CGL EXAM and other competitive exams !!!

Astronomers using the Atacama Large Millimeter/Submillimeter Array (ALMA) have got a view of the water-snow line ..(1)..a star, which they call V 883 Ori, located in the Orion Nebula Cluster. This is a discovery that can inform research on the ..(2)..of planets around a protostar – a star in the making. The research will be published in journal Nature on July 14.The snow line or frost line marks the distance from the protostar where ..(3)..substances condense. There are different snow lines for water, carbon monoxide, ammonia, methane etc. While carbon monoxide-snow lines have been ..(4)..earlier, this is the first time a water-snow line has been found. Its location can determine thearchitecture of planetary systems: rocky planets like the earth form inside this line, while gaseous and giant planets form outside.The discovery has implications for..(5)… For instance, how the earth is really a very dry planet. As Lucas A. Cieza, first author of the paper says, “At the location of the proto-Earth, water was in the form of vapor and couldn’t be ..(6) the planet. The water of the Earth came from comets and asteroids that have a lot of water precisely because they formed outside of the water snow-line.”The researchers also find that the position of the snow line can vary a lot. “When the Solar System formed, the water snow-line was mostly between the orbits of Mars and Jupiter, if it had been much ..(7)..away from the Sun, perhaps the Earth wouldn’t have received enough water-rich comets and asteroids to form the ocean and we wouldn’t have any life on Earth says Dr Cieza.The water-snow line is difficult to observe under normal circumstances because it lies close to the protostar, at about 5 AU In the case of protostar V 883 Ori, the line has moved away from the centre, to a distance of about 42 AU, because the star itself is..(8).. an outburst. The outburst is due to a temporary increase in the rate at which the star grows and consumes the material around it and causes an increase in..(9)…The team discovered it almost by accident. “We expected to see clumps, for example, the forming planets, and spiral arms. Instead, we saw a ring in the disk, so at the beginning we were very confused and a little disappointed! At the end, it turned out that the temperature of the disk at the location of this ring was ..(10).. with the expected temperature of the water-snow line and we had obtained the first-ever image of the water snow line in a protoplanetary disk,” says Dr Cieza.
