The Relation between brain growth and the development of scientific reasoning ability

Theoretically it has been already shown that the development of prefrontal lobe at the onset of early adolescence period is highly correlated with an individual's skills to slow down task-irrelevant data and to get aligned with task-relevant data. These skills are again conditioned by two essential factors – physical experience and social experience – which in turn manipulate the scientific reasoning ability. It also gives power to refuse scientific misconceptions, while allowing scientific theories. Many researches have been conducted in support of this theory and in most of the cases, it retrieves positive result. To know more about it in details, follow this link.

Now it is the time to know about the answers of the previous set.

1. c) ; 2. a) 22 ; 3. b) 48 ; 4. b) 578 ; 5. a) 50 and 30 ; 6. JMQ ; 7. d) guava ; 8. c) Some parrots are birds ; 9. c) Coast-river ; 10. a) .

We Are within Geometrical Shapes - Are We?

Yes, we are within geometrical shapes. Everywhere there is geometry and the entire world is designed with a geometrical shape. Look at your doors when you enter in your house. This is a rectangle. Look at your house. It is a complex combination of rectangular cube. Look at the window. This is also rectangle, sometimes in combination with a half circle on the top. Now look at the inside of a room. The floor is rectangular, the top is rectangular. Your wall clock is a circle. If you look outside, the moon is a circle or more precisely a round sphere. Same is true with the sun. The sky is like a half of a round sphere. Now it's your turn to become creative and find out more and more geometrical shapes around you.
