All known species of penguins are flightless birds that inhabit regions ranging from Antarctica to South America, Africa, and even tropical regions. Fossil evidence reveals that penguins once had the ability to fly, but approximately 60 million years ago, their ancestors evolved powerful wing muscles adapted for swimming and diving. Over time, their bones became denser, making them less buoyant and better suited for underwater hunting. Given these facts, which of the following conclusions is most strongly supported?

A All penguin species currently living are more efficient swimmers than their flying ancestors were.

B The evolution of flightlessness in penguins was an adaptation that improved their ability to hunt underwater.

C Penguins that inhabit tropical regions are more capable of flight than those that inhabit Antarctica.

D All flightless birds evolved from the same ancestral species that originally possessed the ability to fly.

Every year since 1990, the number of patents filed by technology companies in Country X has increased by at least 8 percent. During the same period, the number of new technology startups in Country X has doubled. Furthermore, government data shows that Country X now allocates a larger percentage of its GDP to research and development than any other nation in its region. Based on these facts, which of the following conclusions can be MOST JUSTIFIABLY drawn? A) Country X will become the world's leading economy by 2040. B) The increase in patents filed by technology companies in Country X is correlated with both the growth in new technology startups and increased government investment in research and development. C) Every new technology startup in Country X will eventually file at least one patent within five years of its founding. D) The quality of patents filed in Country X is superior to that of patents filed in any other nation.

All known forms of energy production involve some loss of usable energy, typically as heat. Solar panels convert only about 20 percent of incoming sunlight into electricity. Coal power plants achieve roughly 35 percent efficiency. Even nuclear reactors, despite their complexity, operate at about 33 percent efficiency. Given these constraints and the growing global demand for energy, it is inevitable that energy waste will continue to increase unless fundamentally new conversion technologies are developed. Which of the following most accurately expresses the main conclusion of the argument?

A Solar panels convert only about 20 percent of incoming sunlight into electricity.

B Energy waste will continue to increase unless fundamentally new energy conversion technologies are developed.

C All known forms of energy production involve some loss of usable energy, typically as heat.

D Growing global demand for energy means that coal power plants must be replaced by more efficient technologies.
