Task 2: Listen to the passage and underline linking and incomplete plosion.

At this point, the blend is the consistency of pancake batter, and an agitating blade keeps it that way. Next, nozzles deposit measured amounts of batter on a baking plate that looks like a moving waffle iron. Top plates flip down, and the baking plates roll through a gas-heated oven for a quick bake. The top plates lift up, revealing the cooked waffle patties. Automated arms help transfer the patties to rolling tools. The tools grab the patties and twist them into cones. The cones fall down a shoot and ride an open elevator up and down to cool and harden. The waffle cones slide down another shoot and move into lanes on a conveyor. Automatic fingers adjust their position to prepare them to slide into paper jackets. A computer with a camera eye counts the cones and sends a message to a machine that stacks them in the right increments.

Task 3: Listen to the recording and answer the following two questions.

1. What do sugar cone patties look like?

The patties are fan-shaped and have a flat edge.

2. Why are sugar cones more popular choices for hard ice cream? Sugar cones are stronger than waffle cones.
