Question

levels from industrial emissions.
however, some critics claim that natural
processes, such as volcanic eruptions,
have a larger impact on the environment
than human actions.
which words or phrases in the
excerpt help to link the claim about
human activity causing global
warming to the evidence provided?
\scientists argue\ and \evidence of
this includes\

ising co2 levels\ and \volcanic
eruptions\
\some critics claim\ and \larger
impact\
\however\ and \human actions\

Explanation:

To solve this, we analyze each option:

• Option 1: "Scientists argue" presents a claim, and "evidence of this includes" introduces evidence (like industrial emissions) linking to human activity causing global warming. This fits the need to link the claim to evidence.
• Option 2: "Rising CO2 levels" is part of the context, but "volcanic eruptions" is about natural processes, not linking human activity claim to its evidence.
• Option 3: "Some critics claim" introduces a counter - claim, and "larger impact" is about the counter - claim's assertion, not linking the original claim to evidence.
• Option 4: "However" introduces a counter - argument, and "human actions" is part of the counter - argument's comparison, not linking the original claim to evidence.

Answer:

A. "Scientists argue" and "evidence of this includes"
