Based on my understanding from last meeting about lead and intro, I concluded that lead is the opening paragraph (Sentences) contain 5W 1H of the important information on the news article, the words that use on lead is 30-35 word, lead is a short paragraph that grabs the reader interest. I still confused about what is intro in journalism, i just know that intro is the one sentence that contains about a statement that readers never heard before.
Example:
Lead:
A 40-years-old man was killed and his son and wife was injured in a head-on collision between a bike and a car on Canal road near Bhimpura Village in Vadodara on November 17.
Intro:
Man killed in road accident in Vadodara
