The All-India War Memorial, built in the memory of the Indian soldiers who laid down their lives in the First World War, is known today as _______.

The correct answer is B, Rana Kumbha. The nine storey Vijay Stambha was raised in 1448 by Rana Kumbha of Mewar to mark his victory over Mahmud Khilji of Malwa, and its storeys are covered with sculptured figures of gods and scenes, which is why it is also read as a gallery of Hindu iconography. Option A is wrong because Rana Sanga fought Babur at Khanwa in 1527 and built no such tower. Option C is wrong because Rana Pratap belonged to the later sixteenth century and is remembered for the battle of Haldighati. Option D is wrong because Rana Ratan Singh is linked with the first siege of Chittor by Alauddin Khalji. In the same fort stands the older and smaller Kirti Stambha, a Jain tower of the twelfth century.

The correct answer is C, the Bahai faith. The Lotus Temple at Kalkaji in Delhi was completed in 1986 to a design by the architect Fariborz Sahba, and its twenty seven marble petals are grouped in threes to form nine sides with nine doors, since the Bahai houses of worship are always nine sided and open to people of every religion. Option A is wrong because the best known Jain temples of the region are at Delhi's Lal Mandir and in Rajasthan at Ranakpur and Dilwara. Option B is wrong because Zoroastrian places of worship are fire temples, found mainly in Mumbai and Gujarat. Option D is wrong because Sikh places of worship are gurdwaras, such as Bangla Sahib in Delhi. Remember the number nine with this temple.

The correct answer is B, Edwin Lutyens. India Gate, 42 metres high, was designed by Edwin Lutyens and completed in 1931 as the All India War Memorial, carrying the names of soldiers who died in the First World War and the Third Anglo Afghan War. Option A is wrong because Herbert Baker worked with Lutyens on New Delhi and designed the secretariat blocks on Raisina Hill, but not this arch. Option C is wrong because George Wittet designed the Gateway of India at Mumbai, completed in 1924, and the Prince of Wales Museum. Option D is wrong because William Emerson designed the Victoria Memorial at Kolkata, completed in 1921. Keep the three apart by city: Lutyens in Delhi, Wittet in Mumbai, Emerson in Kolkata. The flame of the immortal soldier that once burned here was merged with the flame at the National War Memorial nearby.

The correct answer is B, Hooghly. The Howrah Bridge joins Kolkata with Howrah across the Hooghly, was opened to traffic in 1943, and is a riveted steel cantilever bridge built without nuts and bolts, which is the detail papers most often test. It was renamed Rabindra Setu in 1965 after Rabindranath Tagore. Option A is wrong because the Damodar, once called the sorrow of Bengal, flows further west and is known for the Damodar Valley Corporation. Option C is wrong because the Subarnarekha flows through Jharkhand, West Bengal and Odisha and carries no bridge of this fame. Option D is wrong because the Teesta flows through Sikkim and north Bengal. Also remember the Vidyasagar Setu, the cable stayed bridge on the same river. Papers also ask which bridge was opened to traffic in 1943, and the answer is this one.

The correct answer is A, Lohit. The Bhupen Hazarika Setu, also called the Dhola Sadiya bridge, runs 9.15 kilometres over the Lohit, a tributary of the Brahmaputra, and joins Dhola in Assam with Sadiya towards Arunachal Pradesh; it was opened in 2017 and is the longest bridge over a river in India. Option B is wrong because the Hooghly at Kolkata carries the Howrah Bridge, now called Rabindra Setu, and the Vidyasagar Setu. Option C is wrong because the Godavari is crossed by the long rail and road bridges at Rajahmundry, which are shorter than this one. Option D is wrong because the Mahanadi is crossed near Cuttack but holds no such record. The longest sea bridge in India, by contrast, is Atal Setu at Mumbai.
