Question

Alisha began the introduction of her speech by saying: like typical new parents, paige and iain lochlan were thrilled when their son lincoln was born. but their elation soon turned to fear as lincoln began to miss important milestones. as an infant, he didn't make eye contact, and a year later he showed no interest in learning how to walk or talk. it wasn't long before paige and iain got the diagnosis every parent dreads—their child is suffering from autism. what kind of supporting material did alisha use in her introduction?
