Rearrange the following sentences in the proper sequence to form a meaningful paragraph; then answer the questions given below them.

(A) Microchip fabrication facilities gradually restored output as raw material supplies normalized, whereas display screen plants continued to suffer from persistent shortages of specialized glass.
(B) Even though both tech components experienced supply bottlenecks, the exact causes and recovery schedules differed substantially.
(C) In contrast, display panel expenses shot up because key manufacturing hubs in Asia faced severe chemical shortages and factory shutdowns.
(D) During the past fiscal year, market prices for both microchips and display screens surged dramatically owing to supply chain crises.
(E) This contrasting pattern demonstrates how distinct industrial vulnerabilities can lead to divergent cost movements among electronic components.
(F) Semiconductor plants in Taiwan endured power outages and water scarcity, resulting in reduced production yields and rising unit costs.

Which of the following sentences should be the LAST sentence after proper rearrangement?

The correct answer is E.

To determine the correct logical order of the sentences and find the final sentence, let us analyze the context and connections between them step-by-step:

1. Sentence (D) [First Sentence]: "During the past fiscal year, market prices for both microchips and display screens surged dramatically owing to supply chain crises."
This statement introduces the central theme of the passage: the supply chain crisis affecting both microchips and display screens. It serves as the logical opening sentence.

2. Sentence (B) [Second Sentence]: "Even though both tech components experienced supply bottlenecks, the exact causes and recovery schedules differed substantially."
This sentence smoothly connects to (D) by elaborating that while both components suffered, the specifics of their causes and recoveries were different.

3. Sentence (F) [Third Sentence]: "Semiconductor plants in Taiwan endured power outages and water scarcity, resulting in reduced production yields and rising unit costs."
This sentence explains the specific cause behind the supply issues of the first component (microchips/semiconductors).

4. Sentence (C) [Fourth Sentence]: "In contrast, display panel expenses shot up because key manufacturing hubs in Asia faced severe chemical shortages and factory shutdowns."
Beginning with the transition "In contrast", this sentence presents the contrasting cause for the second component (display panels).

5. Sentence (A) [Fifth Sentence]: "Microchip fabrication facilities gradually restored output as raw material supplies normalized, whereas display screen plants continued to suffer from persistent shortages of specialized glass."
This sentence discusses the differing recovery schedules referred to in sentence (B), explaining how microchip output recovered while display panel production remained troubled.

6. Sentence (E) [Sixth/Last Sentence]: "This contrasting pattern demonstrates how distinct industrial vulnerabilities can lead to divergent cost movements among electronic components."
Sentence (E) begins with "This contrasting pattern demonstrates...", synthesizing the entire discussion into a conclusive summary. Thus, it naturally serves as the concluding (LAST) sentence of the paragraph.

The correct coherent order of sentences is D – B – F – C – A – E.

Therefore, sentence (E) is the LAST sentence after proper rearrangement.
