Question

(Jumbled Sentences) Arrange the following to form the best-ordered paragraph.
(i) The Super tag scanner could revolutionize the way people shop, virtually eradicating supermarket queues.
(ii) The face of retailing will change even more rapidly when the fiber-optic networks being built by cable-TV companies begin to be more widely used.
(iii) The scanner would have a double benefit for supermarkets—removing the bottleneck that frustrates most customers and reducing the number of checkout staff.
(iv) An electronic scanner which can read the entire contents of a supermarket trolley at a glance has just been developed.

• A. ii, i, iii, iv
• B. iv, i, iii, ii
• C. iv, iii, ii, i
• D. iii, i, iv, ii

Hint:

For jumbled paragraphs, look for: (1) \textbf{topic-introducing} lines (new invention/recent study), (2) \textbf{general claim}, (3) \textbf{supporting details/examples}, and (4) \textbf{broad wrap-up/future} lines with markers like “even more,” “therefore,” or “as a result.”

Answer 1

The Correct Option is B

Step 1 (Find the natural opener): Sentence (iv) introduces a {new development} (“has just been developed”) and names the core object (“an electronic scanner”). Such “announcement” sentences usually start a paragraph because they establish the topic and time frame.
Step 2 (Follow with the immediate impact): Once the device exists, the writer projects its {primary effect}. Sentence (i) directly evaluates that impact—“could revolutionize the way people shop,” and it links to the scanner’s function (“virtually eradicating queues”). Thus, (i) logically elaborates the promise implied by (iv).
Step 3 (Add specific benefits): Sentence (iii) drills down into concrete advantages for supermarkets: (a) removing the queue “bottleneck” (tying back to (i)), and (b) reducing checkout staff. Hence, (iii) is a natural consequence/detail layer after the broad claim in (i).
Step 4 (Conclude with wider context and future acceleration): Sentence (ii) broadens the scope beyond a single store to the {entire retail sector}, using the forward-looking marker “will change even more rapidly when…”. The phrase “even more rapidly” presupposes that change is already underway (as stated in (i)–(iii)), making (ii) an apt concluding, future-oriented sentence.
Step 5 (Reject other orders): \begin{itemize} \item (a) starts with {ii}—a future acceleration clause that lacks an antecedent; “even more rapidly” sounds ungrounded without earlier change.
\item (c) places {iii} immediately after {iv}, skipping the general claim in (i) that motivates the listed benefits.
\item (d) begins with {iii} (a detail) before introducing the device itself—illogical sequence. \end{itemize} Conclusion: The coherent flow is (iv) introduction $\rightarrow$ (i) sweeping effect $\rightarrow$ (iii) specific benefits $\rightarrow$ (ii) sector-wide acceleration, i.e., iv, i, iii, ii.
