Here's the transcript for the listening exercise from last week's lesson. I've left a few gaps for you to fill.
(It) turns out that more than 10% of people, or about 10%, are left-handed. If both parents are right-handed, there's about a 2% chance your child is going to be a _____. If one parent is left-handed, it's about 17%, and if both parents are lefties, there's about a 50% chance your child is also going to be left-handed, with guys _____ twice as often left-handed as girls.
So how do you tell what your child is going to be? (Well) when your baby is about six months of age, he or she may _____ to reach with their right hand, but very quickly will bring out their left hand, and it's not until a baby or a _____ is two years of age that we can really determine hand preference.
