Read the passage and answer the questions that follow.
Every winter, hundreds of humpback whales migrate long distances from their high latitude feeding grounds in the Arctic and Antarctic to warmer tropical regions to breed and give birth. The newborn calves, which drink over 52 gallons of milk every day, have only a few months to gain the body fat needed to keep swimming back to cooler waters in summer. How the babies signal hunger and avoid predators during these early months has always been a mystery to scientists.
"We know next to nothing about the early life stages of whales in the wild, but they are important for the calves' survival during the long migration to their feeding grounds," says study lead author Simone Videsen of the University of Aarhus, Denmark. "These early life stages of wild whales are so confusing because they're an aquatic animal. We can't follow them around all the time to see what they're doing."
Studies revealed that instead of crying loudly like their human counterparts, humpback calves signal their hunger by gently nudging their mothers or uttering soft grunts and squeaks. The moms answer the requests by responding with quiet calls.
The team believes these quiet conversations help whale mother keep track of their young in murky waters without being overheard by dangerous threats. According to Videsen, "Potential predators, such as killer whales could listen to their conversations and use that as a clue to locate the calf and attack on it."
The scientists think that the low audible conversation also keeps mate-seeking males at bay, allowing the females to focus on nurturing the newborns before the tough, 5,000-mile journey back to the feeding grounds in the Antarctic.
How are the quiet calls helpful to the whales? The quiet calls help mother whales to ___________________.

Akeep track of their calves, and keep dangerous threats and mate-seeking males away
Battract male whales who are seeking mates
