Analyse historique : Rosa Parks et droits civiques

Analyze the following historical text segment. Note that the text contains errors in verb tenses, subject-verb agreement, and historical facts.

'In $1955$, Rosa Parks refuse to move on a bus, which starts the boycott. Today, historians note that this event is leading to major changes. Currently, Martin Luther King Jr. is $26$ years old when he leads the Montgomery Bus Boycott. The movement aims for equality, and we calculate the duration of the boycott as $D = 382$ days.'

1. Correct the paragraph: Rewrite the sentences about Rosa Parks and Martin Luther King Jr. using the Past Simple to reflect historical reality.
2. Address the factual error regarding Martin Luther King Jr.'s age: If he was born in $1929$, calculate his true age during the $1955$ boycott ($A = 1955 - 1929$).
3. Use the variable $D$ provided to express the duration in weeks, rounding to the nearest integer ($W = \\frac{D}{7}$).
