Answer:
Stone were used
Bone
Explanation:
Throughout the Paleolithic, humans were food gatherers, depending for their subsistence on hunting wild animals and birds, fishing, and collecting wild fruits, nuts, and berries. The artifactual record of this exceedingly long interval is very incomplete; it can be studied from such imperishable objects of now-extinct cultures as were made of flint, stone, bone, and antler. These alone have withstood the ravages of time, and, together with the remains of contemporary animals hunted by our prehistoric forerunners, they are all that scholars have to guide them in attempting to reconstruct human activity throughout this vast interval—approximately 98 percent of the time span since the appearance of the first true hominin stock. In general, these materials develop gradually from single, all-purpose tools to an assemblage of varied and highly specialized types of artifacts, each designed to serve in connection with a specific function. Indeed, it is a process of increasingly more complex technologies, each founded on a specific tradition, that characterizes the cultural development of Paleolithic times. In other words, the trend was from simple to complex, from a stage of nonspecialization to stages of relatively high degrees of specialization, just as has been the case during historic times.
In the manufacture of stone implements, four fundamental traditions were developed by the Paleolithic ancestors: (1) pebble-tool traditions; (2) bifacial-tool, or hand-ax, traditions; (3) flake-tool traditions; and (4) blade-tool traditions. Only rarely are any of these found in “pure” form, and this fact has led to mistaken notions in many instances concerning the significance of various assemblages. Indeed, though a certain tradition might be superseded in a given region by a more advanced method of producing tools, the older technique persisted as long as it was needed for a given purpose. In general, however, there is an overall trend in the order as given above, starting with simple pebble tools that have a single edge sharpened for cutting or chopping. But no true pebble-tool horizons had yet, by the late 20th century, been recognized in Europe. In southern and eastern Asia, on the other hand, pebble tools of primitive type continued in use throughout Paleolithic times.

The correct answer will be B. compare many people's scores on that measure with their job performance
The accuracy with which a method measures what it is intended to measure is referred to as its validity. If research has high validity, it produces results that correspond to real physical or social properties, characteristics, and variations. One sign that the measurement is valid is high reliability.
We will look at three different types here: face validity, content validity, and criterion validity are all types of validity.
This is an imcomplete question the complete question will be
Which of the following is one way to determine whether a measurement is valid?
a. compare one person's score on that measure with his or her job performance
b. compare many people's scores on that measure with their job performance
c. compare the reliability and validity scores for a group of people
d. compare many people's overall job performance
