Answer:
The answer is c. a hypothesis.
Explanation:
A hypothesis is a possible explanation for a phenomenon that can and has yet to be tested. Hypotheses are usually made through observation, and the understanding of previous scientific theories.
In the passage, Professor Delano's hypothesis can be tested by analysing data about a sample of workers. It was also based on the genetic approach to mate choosing, a well-researched scientific theory.
All members of the clade thyreophoran were quadrupedal (walked on 4 legs).
The statement is True.
An order of armoured ornithischian dinosaurs known as Thyreophoran existed from the Early Jurassic through the end of the Cretaceous period. The body armour arranged in rows along the body is a distinguishing feature of thyreophoran.
The well-known Stegosauria, or plated dinosaurs, and Ankylosauria, or armoured dinosaurs, as well as their more primitive members, such Scutellosaurus and Scelidosaurus, make up the majority of the Thyreophora.
The majority of ankylosaurs, including Euoplocephalus, Nodosaurus, and Palaeoscincus, walked close to the ground on short, stocky legs in a quadrupedal (4) stance and had relatively low and wide body shapes. The length of the rear legs was greater than the length of the front legs, like in stegosaurs, although not to the same degree as in Stegosaurus.

Teaching physical education was the earliest identifiable American physical activity profession and was established in the late 19th century
The earliest identifiable American physical activity profession, teaching physical education, was established in the late 19th century during a period of high interest in physical activity among the general public
More about American physical education:
What was initially referred to as "Physical Culture" emerged in Europe and the America during the nineteenth century, resulting in a fundamental reorientation of life and cultural ideals in the United States by the turn of the twentieth century. Controlled and organised physical activity has been an important part of American life since then, symbolising a more perfectly egalitarian society and contributing to notions of continuing exceptionalism in a rapidly changing and sometimes threatening world.
