The given sentences, when properly sequenced, form a coherent paragraph about recent signs of recovery in the Indian economy after major disruptions. Sentence 1 is fixed as the opening. Choose the most logical order of sentences A, B, C, and D.

Introduction / Context:
This parajumble discusses the Indian economy and asks why it might appear to have returned to health. Sentence 1 suggests that one could think the economy is looking rosy again. The remaining sentences describe evidence of recovery and recall the two major disruptions that the economy had to overcome.

Given Data / Assumptions:
Sentence C begins with It seems to have recovered from two enormous disruptions, clearly referring back to the Indian economy mentioned in sentence 1. Sentence A then specifies these disruptions as the decision to withdraw most currency in circulation and the poorly planned rollout of the new goods and services tax. Sentences B and D list positive indicators of recovery. B mentions the Purchasing Managers Index expanding at its fastest pace in five years and a credit rating upgrade. D states that exports are no longer declining and have even risen by 30 percent in the latest month of data.

Concept / Approach:
The logical structure of the paragraph is first to state that the economy appears healthy, then to say that it has recovered from serious shocks, then to identify those shocks, and finally to provide concrete output data that support the impression of recovery. We also watch for pronouns like it, which clearly refer to the economy mentioned in the previous sentence.

Step-by-Step Solution:
First, sentence C must follow sentence 1 because it continues the thought with it seems to have recovered, where it obviously refers to the Indian economy in the opener.Second, sentence A naturally comes after C because it spells out the two enormous disruptions just mentioned: the demonetisation move and the introduction of the goods and services tax.Third, after naming the disruptions, the paragraph should present evidence of recovery. Sentence D offers a clear data point about exports that supports the idea of improvement.Fourth, sentence B further reinforces this picture with other indicators, such as the Purchasing Managers Index and a rating agency upgrade.Therefore, the most coherent order after sentence 1 is C, A, D, B, which is captured by option CADB.

Verification / Alternative check:
Reading in order 1, C, A, D, B gives a smooth narrative: the economy seems to have recovered, it faced two disruptions, those disruptions are named, exports have improved, and an index plus a rating agency confirm the positive trend. By contrast, if we begin with A immediately after 1, the phrase two enormous disruptions in C would appear without clear reference later, and the paragraph would feel less tightly constructed.

Why Other Options Are Wrong:
Option ABDC starts with A before C, so the term two enormous disruptions appears in C after the details have already been given, which reverses the natural order. Option ACBD also misorders the explanation and uses the indicators before clearly framing the idea of recovery from disruptions. Option BCDA begins with B, jumping directly into data without first mentioning that the economy has recovered from anything, so the link to disruptions becomes weak. These sequences make the argument less coherent than CADB.

Common Pitfalls:
A common mistake in parajumble questions is to start with data rich sentences because they feel important. However, writers usually frame the issue first and then support it with numbers. Another pitfall is to ignore logical signposts like two enormous disruptions, which strongly suggest that an explanation is coming immediately afterwards. Always look for such signals when choosing the correct sequence.

Final Answer:
The correct sequence after sentence 1 is C, A, D, B, so the answer is CADB.
