In this error spotting question, read the sentence and identify the part that contains an error. The sentence is: "Sometimes, when you are used to see a player in the commentary box over a long period, you tend to forget what a great player he was."

Introduction / Context:
This question tests your understanding of correct verb forms after certain expressions, particularly "used to". The sentence talks about watching a former player as a commentator for a long time and forgetting how great he was as a player. You must identify which segment contains a grammatical error related to "used to".

Given Data / Assumptions:

• Sentence: "Sometimes, when you are used to see a player in the commentary box over a long period, you tend to forget what a great player he was."
• Segments:
  • A: Sometimes, when you are used to
  • B: See a player in the commentary
  • C: Box over a long period, you tend to
  • D: Forget what a great player he was
• Option E: No error.
• The expression "be used to" is followed by a noun or a gerund (verb plus ing).

Concept / Approach:
There are two different structures with "used to". The first is "used to" plus base verb, which talks about a past habit: "He used to play cricket." The second is "be used to" plus a noun or gerund, meaning "be accustomed to": "He is used to playing cricket." In this sentence, we have "you are used to", which is the second structure and therefore must be followed by a noun or an ing form of a verb. The phrase "see a player" uses the base form "see", which is incorrect here. It should be "seeing a player".

Step-by-Step Solution:
Step 1: Identify the structure "you are used to" in segment A. This is "be used to", which describes being accustomed to something. Step 2: Recall that "be used to" must be followed by a noun or gerund: "used to noise", "used to walking", and so on. Step 3: Segment B begins with "See a player in the commentary". The verb "see" is in base form, not gerund form. Step 4: To be grammatically correct, segment B should read "seeing a player in the commentary". Step 5: Segments C and D are grammatically sound and correctly express the rest of the idea.

Verification / Alternative check:
Rewrite the corrected sentence: "Sometimes, when you are used to seeing a player in the commentary box over a long period, you tend to forget what a great player he was." This reads naturally and maintains the intended meaning. If we changed segment A to "you used to", we would need to change the structure of the sentence entirely. Since the rest of the sentence clearly uses "be used to" in the present, the simplest and correct fix is to adjust the verb form in segment B.

Why Other Options Are Wrong:
Segment A correctly introduces the condition "Sometimes, when you are used to".

Segment C correctly continues the thought with "box over a long period, you tend to", joining the clause smoothly.

Segment D correctly uses "forget what a great player he was" and uses past tense "was" to refer to his playing days.

" No error" is incorrect because the phrase "used to see" in this structure is grammatically wrong.

Common Pitfalls:
A typical confusion arises because learners mix up "used to" (past habit) and "be used to" (be accustomed to). The first takes a base verb, the second takes a noun or gerund. To avoid mistakes, always check whether there is a form of "be" (am, is, are, was, were) before "used to". If there is, follow it with an ing form when you use a verb. If there is no "be" verb, you are probably talking about a past habit and should use the base verb.

Final Answer:
The error is in segment B, which should be "seeing a player in the commentary", so option B is correct.
