Answer:

the last half of the second year

Explanation:

The last half of the second year in an infant means the last 6 months, between July - December of the year the infant will clock two years. That is the remaining six months preceding his/ her two years birthday.

At this time the sensory and motor neurons of the infant has tremendously developed in such a way that he/she has the ability to grasp an object with the use of the arms. Several attempts would have been made before this time, where the infant would have made attempts of grasping objects with one hand.

It Should be understood that, based on the research conducted, it has been discovered that most infants successfully hold or grasp things with their right hand or arm more than the left one.

Ned wants to demonstrate that global warming is indeed a real occurrence within our world. ned's speech will be addressing a:
Rudik [331]
This is a tricky question, since it depends what usage of the words is meant, but the best answer is: a fact. 

He is treating the topic of whether the global warming is real or not and all our evidence strongly points to the fact that it is, in fact, real. 

In the common usage of the word, we are talking about a fact - the best answer is b). 


However, in science, the facts are referred to as "theories" - even gravity which we all experience, is known as a "theory", so there are also good arguments for the option c). 

However, as I said, in the common understanding of the word, these theories are facts - if we disprove them, we stop calling them theories, and they are only hypotheses.
