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

(A) Artificial intelligence and robotics are very recent technologies and risks for our world.
(B) They may also inherit the full nature of creatures.
(C) When humans see the past histories of AI and robotics, human beings can examine and understand the objectives and intentions of them to make life easy and assist human beings within different circumstances and situations.
(D) However, currently and in the near future, due to the change in the attitude of robotic and AI inventors and experts as well as based on the AI nature that their capacity of environmental acquisition and adaptation, they may become predators and put creatures at risk.
(E) They are developing their capacity dramatically and shifting their origins of developing intention to other dimensions.
(F) Thus, finally they will create their new universe or the destiny of our universe will be in danger.

Which of the following should be the FIRST sentence after rearrangement?

The correct answer is Option A.

Sentence A should be the first sentence after rearrangement.

Understanding the Paragraph's Theme:
The passage is about Artificial Intelligence and Robotics — their origins, growth, potential dangers, and ultimate consequences for the world.

Why Sentence A must come FIRST:
Sentence A reads: "Artificial intelligence and robotics are very recent technologies and risks for our world."
This sentence serves as the introductory/topic sentence of the paragraph. It introduces the two central subjects — AI and robotics — for the very first time, and frames the overall theme by mentioning both their recency and their risk. A well-structured paragraph always begins with a topic sentence that sets the context for everything that follows.

Logical Flow of the Full Paragraph:
Once we recognize A as the opener, the rest of the sequence falls into place naturally:

A → C → E → D → B → F

• A — Introduces AI and robotics as recent technologies and risks. (Topic sentence — sets the stage)
• C — Refers back to "them" (AI and robotics introduced in A), discussing how humans can study their past history to understand their intentions. (Historical perspective)
• E — Explains how these technologies are developing dramatically and shifting their original intentions. (Growth/evolution)
• D — Discusses how, due to changing attitudes and AI's adaptive nature, they may become predators and pose risks. (Rising danger)
• B — States they may inherit the full nature of creatures. (Escalation of threat)
• F — Concludes that they will create their own universe or put our universe's destiny in danger. (Ultimate consequence/conclusion)

Key Reasoning Trick for Paragraph Ordering:
In such rearrangement questions, always look for the sentence that:

1. Introduces the main subject without using pronouns like "they" or "them" (since those refer back to something already introduced).
2. Provides the broadest, most general statement about the topic.
3. Does not logically depend on any other sentence to make sense.

Sentence A fulfills all three criteria perfectly — it names AI and robotics explicitly, makes a general introductory claim, and requires no prior context to be understood. Hence, A is the FIRST sentence.
