Input: Article: A lone naked human is at a physical disadvantage to other comparable apex predators in areas such as speed, bone density, weight, and physical strength. Humans also lack innate weaponry such as claws. Without crafted weapons, society, or cleverness, a lone human can easily be defeated by fit predatory animals, such as wild dogs, big cats and bears (see Man-eater). However, humans are not solitary creatures; they are social animals with highly developed social behaviors. Early humans, such as Homo erectus, have been using stone tools and weapons for well over a million years. Anatomically modern humans have been apex predators since they first evolved, and many species of carnivorous megafauna actively avoid interacting with humans; the primary environmental competitor for a human is other humans. The one subspecies of carnivorous megafauna that does interact frequently with humans in predatory roles is the domestic dog, but usually as a partner in predation especially if they hunt together. Cannibalism has occurred in various places, among various cultures, and for various reasons. At least a few people, such as the Donner party, are said to have resorted to it in desperation.

Now answer this question: What physical disadvantages do humans have against other apex predators?

Output: speed, bone density, weight, and physical strength

Input: Article: On 23 February, the 28th Marine Regiment reached the summit of Suribachi, prompting the now famous Raising the Flag on Iwo Jima picture. Navy Secretary James Forrestal, upon seeing the flag, remarked "there will be a Marine Corps for the next 500 years." The flag raising is often cited as the most reproduced photograph of all time and became the archetypal representation not only of that battle, but of the entire Pacific War. For the rest of February, the Americans pushed north, and by 1 March, had taken two-thirds of the island. But it was not until 26 March that the island was finally secured. The Japanese fought to the last man, killing 6,800 Marines and wounding nearly 20,000 more. The Japanese losses totaled well over 20,000 men killed, and only 1,083 prisoners were taken. Historians debate whether it was strategically worth the casualties sustained.

Now answer this question: What marine regiment reached the summit of Mount Suribachi?

Output: 28th
