English grammar — Spot the error (choose the segment that contains a grammatical error; choose ‘‘No error.’’ if the sentence is correct). Sentence: We now look forward for some great achievements which to some extent can restore the country's prestige once again.

Introduction / Context:
This problem checks knowledge of fixed prepositional patterns and redundancy. The phrasal verb “look forward to” requires the preposition “to,” not “for.”

Given Data / Assumptions:

• “Look forward to” must be followed by a noun or a gerund.
• Other parts of the sentence are stylistically acceptable, though “once again” may be redundant with “restore.”

Concept / Approach:
Identify the collocation error first, then review remaining segments for grammar. Even if additional style improvements are possible, error-spotting focuses on the clearly incorrect chunk.

Step-by-Step Solution:

Verification / Alternative check:
Corrected sentence: “We now look forward to some great achievements which, to some extent, can restore the country’s prestige.”

Why Other Options Are Wrong:

• B, C, and D do not contain a clear grammatical error; A does.

Common Pitfalls:
Confusing “look forward to” with verbs that take “for.” Remember: “to” here is a preposition, so it takes a gerund or noun afterward.

Final Answer:
We now look forward for
