Answer:
changes in human genetic characteristics
Explanation:
Since the Flynn effect sees the increase in IQ scores with factors directly impacting: changing communicating technologies- This means people are engaged in more intellectually demanding activities in the context of learning, updating and managing information.
Similarly, with increased opportunities for educating, learning comes at the hands of most people, and this enables a general population to become more skills in scoring a higher IQ.
Other development factors, like having better nutrition, will account for brain development and will lead to manifest as people more capable of dealing with abstract reasoning. If the reduction in family size coincides with having a better quality of life, then people are expected to become more proficient and score higher.

A pictograph is a graphic representation of something. It is used in ancient times as a means of writing. Pictographs are direct representation of tangible or visible things. For example, I can daw a picture of a cow. That cow on paper could be a pictograph of a real cow. However, if the symbol already represents an idea, it's called an ideogram. For example, if I want to illustrate love, I can draw a heart shape. I can't see or touch love. I know that the human isn't shaped like in the drawing. However, I know the symbol represents the idea of love.
The answer: FALSE. Ideograms represents an idea.
