Why might a reader want to be cautious when reading an unauthorized biography?

As a reader, you would want to be cautious when reading an unauthorized biography because unless the information is cited and verified as correct, you don't know if the information provided in the biography is correct.

Explanation:

For example, if you read in an unauthorized biography that Rosa Parks was born on March 16th, 1914, you would have no clue that this is in fact, incorrect. This is why you would need to either find a new biography that is authorized and verified or double check the information given.

Hope this helped!

i go to the store and buy some cheese,suddenly there was akward silence.   out of no where comes a ninja, and he takes an apple, and chokes the cashier, until he passes out.   the disapeared in a puff of smoke.   the cashier went to the doctor, and everything was fine again.   they all lived happily ever after without anymore ninjas.

the end

go to buy cheese= exposition

akaward silence= rising action

ninja chokes the cashier= climax

cashier goes to the doctor= falling action

they live happily ever after= resolution
