Show answer & explanation
Correct answer: C
Concept
An automatic identification technology is named after the physical carrier it uses to move data through the air, not after the object it identifies. The data carrier itself — the small device attached to the item — is by definition built from exactly two functional parts: a storage-and-processing element that holds the identity data, and a radiating element that couples that data onto the carrier waves. Filling a definition paragraph like this one is therefore a matter of matching each blank to the role the sentence itself assigns it: technology name, device name, storage part, radiating part.
Application
The paragraph assigns a distinct role to each of its four blanks, so take them in order:
First blank, "Radio ___ Identification Systems": the sentence is naming the technology, and the carrier it moves data on is the radio frequency. This blank takes B (frequency), giving Radio Frequency Identification.
Second blank, "The ___ is made up of": the sentence needs the device just described as holding the stored information and being readable from several metres away. That device is A (tag).
Third blank, "a(n) ___ to store and process data": storing and processing data are the functions of an integrated circuit, so this blank takes D (microchip).
Fourth blank, "a(n) ___ to receive and transmit data": receiving and transmitting radio signals is the function of the radiating conductor, so this blank takes C (antenna).
Cross-check
Frequency describes a property of the carrier wave, not a physical part, so it cannot occupy either blank introduced by "is made up of".
Tag names the whole device, so it cannot also be listed among the parts that same device "is made up of".
Microchip and antenna are not interchangeable: storing and processing is silicon logic, while receiving and transmitting is a radiating conductor, so swapping the two contradicts the verbs the sentence uses.
Reading the four blanks in order therefore gives frequency, tag, microchip, antenna — the sequence B, A, D, C.
