Answer 1

For the first part:

Try to overlap the "lines" with the grid in the center, then observe the cells which are not covered by the lines!

We will get:

The letters! Also do you notice the labels are "half" of some shapes i.e.

- Half circle: T
- Half pentagon: T
- Half rhombus: H
- Half square: S
- Half triangle: M

After that, for the second part:

It is simply a rebus i.e.

- Half pentagon: COUCH
- Half circle: WASTE
- Half triangle: SHELL
- Half square: LIGHT
- Half rhombus: TEARING

And combining them:

If we match both halves, and replace the x-th letter by its first part where x is denoted on the right side of the rebus, we will have:

TOUCH, TASTE, SMELL, SIGHT, HEARING

Thus the final answer for this puzzle is our five SENSES! (Or do you believe in sixth sense?)
