It would seem unlikely that anything weighing 45 tons would move easily, but that is just what the male humpback whale does every winter. With a deft gracefulness, the massive sea mammal travels from the Gulf of Alaska to Hawaii in less than two months. Part of the baleen whale species, the male humpback can stretch 40 to 52 feet in length and weigh up to 45 tons. Even with those dimensions, the whales are able to propel themselves out of the ocean in a breach, revealing 40% to 90% of their bodies. The purpose of the breach is not completely understood, but different theories abound to explain this behavior, such as assertions of dominance, warnings to other whales in the pod, or as a form of courting.
The latter explanation, perhaps, makes the most sense concerning the North Pacific male humpback population in that the purpose of their mission is to mate with the females. Approximately two-thirds of the whales residing in the Gulf of Alaska travel more than 3,000 miles to breed and nurse their newborns during a five- to six-month period. The migration is a fierce race among the male humpbacks, who may be tracking a female with other competing males in order to be first in line when they reach the breeding grounds off the coast of Hawaii. A female whale only breeds every two to three years, and the gestation period is 11.5 months. These courting rituals, although turbulent in the social structure of humpback whales, make for entertaining displays for humanspectators watching as the pods of males gather and breach to win the female’s attention.

Explanation
1. What is the best title for this passage?
Keep the passage summary in your mind and go to the answer choices.
(A) focuses only on courting rituals, but the passage covers migration, size, behavior, and multiple theories for breaching, not just courtship. Out.
(B) is tempting but too narrow and implies multiple whale species and breeding locations, whereas the passage centers on male humpbacks and the Alaska-Hawaii migration.
(C) overemphasizes “treacherous journey” details, which the passage doesn’t develop extensively-the tone is more about purpose and behavior.
(E) is too casual and human-centered; the passage’s main subject is whale biology and migration motives, not whale watching.
Only (D) captures the broader scope of the passage, which explains why humpbacks migrate (to breed/nurse), why they breach (possible dominance, warning, or courtship), and the social dynamics during migration.

Passage Map and Summary
1. Main Topic: The surprising agility and long-distance migration of the male humpback whale, focusing on its purpose and behaviors.
2. Key Details about the Whale:
Species: Baleen whale, 40-52 feet long, up to 45 tons.
Behavior: Capable of breaching (propelling 40–90% of body out of water).
Migration: Travels from Gulf of Alaska to Hawaii in <2 months (~3,000 miles).
3. Primary Purpose of Migration: Breeding and nursing newborns over 5–6 months.
4. Explanation for Breaching: Unclear, but theories include dominance, warning, or courtship. Context suggests courtship is primary for males.
5. Social & Reproductive Context:
Summary
Despite their enormous size-up to 45 tons and 52 feet long-male humpback whales exhibit remarkable agility, migrating swiftly from the Gulf of Alaska to Hawaii each winter to breed. Their journey, covering over 3,000 miles in under two months, is driven by intense competition to mate with females, who reproduce infrequently. During this time, males perform dramatic breaches, a behavior possibly linked to courtship, dominance, or communication. This energetic competition, while turbulent for the whales, offers striking displays for human observers.

5. Social & Reproductive Context:
- Males race to track females and secure breeding rights.
- Females breed only every 2–3 years; gestation is 11.5 months.
- The competition creates dramatic displays observable by humans.
