Some parts of a passage have been jumbled up. Select the option that gives the correct sequence.
By 55,000 years ago, modern humans had arrived on the Indian subcontinent.
P: These sites developed into the Indus Valley Civilisation.
Q: After 6500 BCE, evidence of domestication appeared.
R: During 2000–500 BCE, regions transitioned to the Iron Age.
S: The earliest modern human remains date to about 30,000 years ago.

Correct option is D

The correct option is (d) SQPR.

Explanation (Step-by-step logical order):

• The opening line gives the earliest broad timeline: humans arrived by 55,000 years ago.
• S should come next because it continues the early-human timeline by mentioning the earliest modern human remains (about 30,000 years ago).
• Q logically follows because it moves forward to a later historical period: After 6500 BCE, domestication evidence appears.
• P must follow Q because “These sites” refers back to the settlements/locations implied by domestication and early farming developments.
• R comes last as it is the latest time period mentioned: 2000–500 BCE (Iron Age transition).

Why other options are incorrect:

• (a) PQRS: Starts with domestication/Indus civilisation before establishing early remains properly.
• (b) QRSP: Places Iron Age before introducing the Indus development logically.
• (c) RPQS: Begins with Iron Age, which is chronologically much later than the other statements.

So the correct answer is (d)
