In the question of determining which chairs will rock TO AND FRO, we are analyzing the design and structure of the chairs in the presented figures. Specifically, we need to identify which chairs have a base that allows for rocking motion, typically characterized by curved legs or a mechanism that enables such movement.
By examining the images:
- - This chair features a curved base typically associated with rocking chairs, allowing it to move back and forth. Therefore, it can rock TO AND FRO.
- - This chair appears to have a standard flat base, which is usually not conducive to rocking motion.
- - Similar to Fig 2, this chair has a flat base and does not exhibit features typical of a rocking chair.
- - This chair also displays a curved base, enabling the rocking motion. Thus, it can rock TO AND FRO.
Therefore, the chairs shown in
andare designed to rock TO AND FRO.
