Which of the following sentences is from a firsthand biography?

I completed my first concerto when I was fifteen
I wanted to go to the Olympics but did not make it
I want to tell you about the greatest man who ever lived
I joined the dance company in 1995

I completed my first concerto when I was fifteen.

The sentence "I completed my first concerto when I was fifteen" is from a firsthand biography.

To determine which of the sentences is from a firsthand biography, you need to understand what a firsthand biography is. A firsthand biography is a biography written by the subject themselves or by someone who directly interacted with the subject and witnessed events described in the biography.

Let's analyze each of the sentences to determine if they come from a firsthand biography:

1. "I completed my first concerto when I was fifteen."
This sentence is written from the first-person perspective, suggesting that the speaker is the subject of the biography. Therefore, it is likely from a firsthand biography.

2. "I wanted to go to the Olympics but did not make it."
This sentence is also written in the first-person perspective, indicating that the speaker is the subject of the biography or a person closely involved with the subject. It could be from a firsthand biography.

3. "I want to tell you about the greatest man who ever lived."
This sentence uses the first-person pronoun "I" but doesn't necessarily suggest a direct involvement or personal experience with the subject. It is not explicit enough to determine if it is from a firsthand biography.

4. "I joined the dance company in 1995."
Similar to the previous sentences, this sentence uses the first-person pronoun "I." Although it implies personal involvement, it doesn't provide enough information to determine if it is from a firsthand biography.

Based on the analysis, both sentences 1 and 2 could be from a firsthand biography since they are written from the first-person perspective and suggest personal experiences. However, without further context, it is challenging to determine with certainty which sentence is specifically from a firsthand biography.
