Answer:
The correct answer is D. Although there is variability in the ages at which infants acquire various skills, the order in which skills are acquired is fairly consistent.
Explanation:
An infant's motor development occurs from the center of the body, from the top to the bottom. This means they control their heads, for example, before their feet.
It is fair to say that the ages in which an infant acquires the skills are consistent; he/she starts to develop gross and fine skills regularly.
Answer:
Boats of the Neolithic era were very simple. They were essentially rafts, made of easy to find materials such as wood.
In the Neolithic, there were many cultures that built boats, and sailed across the sea, but mostly for relatively short distances. Interoceanic navigation was essentially null.
Boats of the modern era have evolved a lot. From sailing boats, to large rowing boats like the Viking longships, to mechanical boats of the modern era. This evolution is to be expected since boats are among the first human inventions in history, dating back to thousands of years before the Neolithic Revolution.
