Answer: Archaeopteryx

Explanation: The Archaeopteryx is known as the transitional form between dinosaurs and birds. Archaeopteryx had features that links it to present-day reptiles and birds. It had feathered wings but a bony tail, and is believed to have evolved into birds in 10 million years.  

The Archaeopteryx had a flat sternum, unlike modern day birds. Birds which fly have a keeled sternum and it is possible that the Archaeopteryx did not use sustained flight as a method of movement and the feathers were mostly a means of insulation.

Paolo is training for a triathlon, a timed race that combines swimming, biking, and running. Consider the following sentence: Be
GalinKa [24]

Answer:

Many decisions are taken at the margin

Explanation:

Many decision are taken at the margin.

He makes small changes at the margin in the number of hours spent training on each activity.

Paola and his wife both realise that increasing time spend in the pool will decrease his total triathlon time.

His time is fixed (20hrs) and anytime he wants to spend extra on one activity, i means that he cannot spend time on another (this is known as opportunity cost).

They are both on the same page in terms of trying to improve Paolo's total time (exploiting opportunities to makes themselves better off).

1hour switch in Paolo's point of view isa major change, whereas his wife recommends a wholesale change.

Paolo realises that as he spends more time in the pool improving his swim time, his run and cycle times will take a hit. As he swims more, his improvement is likely to slow down, while spending less time on cycling and running will cost him more in terms of time.

Hence Paolo is looking at the margins.

His wife on the other hand, is not, she is ignoring the interaction, may be forgetting the ncreasing deterioration in terms of time of the other 2 legs

Veseljchak [2.6K]

Answer:

The idea of Social Contract Theory

Explanation:

The Social Contract Theory was addressed by several philosophers, but the one who stated that people can resist and remove rulers who violate their purposes it was John Locke. Locke was against the idea that a ruler should have absolute power over decisions related to the well-being of the people. But he agreed that it was necessary to have an impartial power of judgment that was beyond the citizens. In general, however, the Social Contract Theory indicates a class of theories that try to explain the paths that lead people to form States and/or maintain the social order.

aliya0001 [1]

Answer:

The correct answer would be option A) Socratic educators.

Explanation:

The Socratic Method of Education focuses on the purpose of giving students the chance to acquire knowledge through developing an idea which may be established upon their concerns, combined with moral understanding and truth upon experiences, constructing then an ideal epic myth upon peculiar facts of living. This way students can symbolically identify themselves with their family members in a leading role, providing them with the opportunity to grow as individuals and for the goodness of society.
