Chennai to Get Projects Worth Over ₹13,000 Crore on 11 October

The correct answer is over ₹13,000 crore. The announcement states that the projects taken up together at Chennai in Tamil Nadu carry a combined value of more than ₹13,000 crore, and that they cover metro rail, national highways, railways, ports, petroleum and education. Option A names ₹3,700 crore, which is only the figure for the national highway projects in the State and not the whole package, so it understates the outlay badly. Option B gives ₹8,500 crore, a figure that does not belong to any part of this announcement at all. Option D raises the sum to ₹21,000 crore, which is well above what the package is worth. Within the total, the metro stretch alone accounts for about ₹4,900 crore, the highway works about ₹3,700 crore, the rail works more than ₹750 crore and the lube oil base stocks plant nearly ₹1,620 crore, which shows how the larger figure is made up.

The correct answer is Phase II of Chennai Metro, with a double-decker structure of 3.7 km. The stretch from Poonamallee to Vadapalani is part of the second phase of the Chennai Metro Rail Project, it was built at a cost of about ₹4,900 crore, and its distinguishing feature is a double-decker structure running 3.7 km, along with advanced signalling meant to support driverless operations. The corridor is expected to cut daily travel time and improve the link between the fast-growing western suburbs of the city and the centre. Option A wrongly places the stretch in the first phase and invents an underground tunnel. Option C assigns it to a suburban rail system, which is not what the announcement describes. Option D moves it to a third phase and adds a floating station, a feature nowhere mentioned. Only option B matches both the phase and the structure.

The correct answer is the Amrit Bharat Station Scheme. The five stations named for inauguration in Tamil Nadu, at Palani, Vellore Cantonment, Ambasamudram, Paramakkudi and Namakkal, have been rebuilt under that scheme and are being opened as Amrit Stations, as part of railway works worth more than ₹750 crore that also include the Karaikal-Peralam line and three rail flyovers in and around Coimbatore. Option B, the Adarsh Station Scheme, is a different railway programme and is not the one named here. Option C, Setu Bharatam, deals with road bridges and level crossings on national highways rather than station buildings. Option D, Bharatmala Pariyojana, is a highway development programme and has nothing to do with station redevelopment. Candidates should link the words Amrit Station to this scheme and remember the five station names.

The correct answer is IIT Madras; C-STROKE, a human ischaemic stroke atlas. The Sudha Gopalakrishnan Brain Centre stands at IIT Madras and is being dedicated to the nation during the Chennai visit. Along with it begins a global scientific mission to map more than 100 human brains into three-dimensional atlases at cellular resolution, covering the whole span of life from the foetal stage to old age. C-STROKE is described as the first atlas of its kind for human ischaemic stroke and carries over 1,000 annotated microscopic sections from a stroke-affected brain, which researchers across the world can use to identify new therapeutic targets. Options B, C and D name other well-known institutions and other kinds of atlases, none of which figures in this announcement. The pairing to remember is the brain centre with IIT Madras and the stroke atlas named C-STROKE.
