**Explanation:**

In this question, we are given a situation where the speaker states that they have not done things that others may consider ________ recording. We are provided with five options: useless, worth, good, historic, and bad. We need to choose the option that best fits the context.

**Useless:** When we say that something is "useless," it means that it has no value or purpose. In this case, the speaker is stating that they have not done things that others may consider ________ recording. If we fill in the blank with "useless," it means that the speaker has not done things which others may consider having no value or purpose when recorded.

**Worth:** When we say that something is "worth," it means that it has value or is deserving of attention, effort, or respect. If we fill in the blank with "worth," it means that the speaker has not done things which others may consider having value or deserving attention, effort, or respect when recorded. However, this does not align with the speaker's statement that they have not done things that others may consider ________ recording.

**Good:** When we say that something is "good," it means that it is of high quality or is morally right. If we fill in the blank with "good," it means that the speaker has not done things which others may consider of high quality or morally right when recorded. However, this does not provide a clear context for the speaker's statement.

**Historic:** When we say that something is "historic," it means that it is important in history or has historical significance. If we fill in the blank with "historic," it means that the speaker has not done things which others may consider having historical significance when recorded. However, this does not provide a clear context for the speaker's statement.

**Bad:** When we say that something is "bad," it means that it is of poor quality or morally wrong. If we fill in the blank with "bad," it means that the speaker has not done things which others may consider of poor quality or morally wrong when recorded. However, this does not provide a clear context for the speaker's statement.

Based on the options provided, the most appropriate answer is option 'A' - useless. This choice aligns with the speaker's statement that they have not done things that others may consider having no value or purpose when recorded.
