Final answer:
The author includes details in the last paragraph to highlight the astronauts' accomplishments with the new spacesuit design, demonstrating the importance of technological advancements in successful lunar exploration.
Step-by-step explanation:
The author most likely includes the details in the last paragraph to show what the astronauts accomplished with the new spacesuit design. The paragraph gives specific achievements from the Apollo missions, such as the collection of nearly 400 kilograms of samples for Earth analysis. Understanding these accomplishments helps illustrate the historical significance of lunar exploration and the progression of scientific understanding that was facilitated by innovations like the spacesuit design and the experiments conducted on the lunar surface. Moreover, detailing the employment of the Apollo Lunar Surface Experiment Package (ALSEP) and the extensive lunar surface analysis by orbiting Apollo command modules underscores the level of scientific work performed, which goes hand-in-hand with the investment in technology such as the spacesuit.
Furthermore, the inclusion of geologist Jack Schmitt in the last Apollo landing demonstrates NASA's commitment to the scientific aspect of lunar exploration and the usefulness of having experts in specific fields take part in the missions. All this information is suggestive of the paragraph's purpose to underscore the achievements enabled by the spacesuit design, among other technologies.
