CAT 2022 Slot 3 — VARC Question 24
The four sentences (labelled 1, 2, 3 and 4) below, when properly sequenced, would yield a coherent paragraph. Decide on the proper sequencing of the order of the sentences and key in the sequence of the four numbers as your answer:
- Various industrial sectors including retail, transit systems, enterprises, educational institutions, event organizing, finance, travel etc. have now started leveraging these beacons solutions to track and communicate with their customers.
- A beacon fixed on to a shop wall enables the retailer to assess the proximity of the customer, and come up with a much targeted or personalized communication like offers, discounts and combos on products in each shelf.
- Smart phones or other mobile devices can capture the beacon signals, and distance can be estimated by measuring received signal strength.
- Beacons are tiny and inexpensive, micro-location-based technology devices that can send radio frequency signals and notify nearby Bluetooth devices of their presence and transmit information.
Answer & solution
Answer: 4312
Easy
Para-jumble about beacons. The natural order is a definition first, then how they work, then a use-case, then the spread across industries.
Opener = 4. "Beacons are tiny and inexpensive... devices that can send radio frequency signals and notify nearby Bluetooth devices..." It defines the term "beacons," so it must come first.
4 → 3. Sentence 3 explains the mechanism: "Smart phones or other mobile devices can capture the beacon signals, and distance can be estimated by measuring received signal strength." It follows the definition with how they are detected.
3 → 1. Now that proximity/distance can be measured, sentence 1 gives the application: "A beacon fixed on to a shop wall enables the retailer to assess the proximity of the customer, and come up with... targeted... communication." It uses the distance idea from 3.
1 → 2 (closer). After the retail example, sentence 2 generalises: "Various industrial sectors including retail, transit... finance, travel etc. have now started leveraging these beacons solutions..." Broadening to many sectors is a fitting conclusion.
