Parajumbles Question 8 - CAT 2022

Question

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.

Smartphones 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.

Correct Sequence: 4312
Explanation: Sentence 4 acts as a definitive topic intro, providing a clear dictionary-style breakdown of what beacons are (tiny, inexpensive micro-location devices emitting radio frequencies). Sentence 3 details the mechanical receiver side of that system, explaining how consumer smartphones pick up those frequencies to calculate proximity. Sentence 1 scales this technical capability up into commercial market adoption, listing the various economic sectors (retail, transit, travel) deploying beacon solutions. Sentence 2 closes by spotlighting a localized case study within one of those named sectors, showing exactly how a retailer can use a wall-mounted beacon to customize item offers.
FundaMakers Tip: Technical Definition to Practical Use Case. Identify the sentence that outlines a tool's core technical properties (Sentence 4). Track how it transmits data (Sentence 3), its commercial target markets (Sentence 1), and end with a practical example of it running live on the ground (Sentence 2).

Find the main idea presented in a sentence before looking for its explanation.
Look for elaboration—the explanation usually provides additional details, reasons, or clarification.
Identify defining statements where one sentence introduces a concept and the next explains it.
Watch for examples that support or illustrate the main idea.
Check for logical continuity to ensure the explanation directly builds on the preceding idea.
Treat the idea and its explanation as a pair while determining the overall sequence of the paragraph.
