Correct Answer: poke

Solution : The correct choice is the second option.

Explanation:
Shove and poke both involve a degree of physical pushing, but a shove tends to be more forceful and aggressive, while a poke is a gentler, more directed push. It's a matter of intensity, i.e., a shove is a stronger, more vigorous push, while a poke is a lighter, more targeted one.

The meanings of the other options are as follows:

• Shout means to speak loudly or yell.
• Pull means to exert force in the opposite direction of a push, drawing something towards oneself.
• Halt means to stop or come to a sudden pause.

Therefore, the correct answer is poke.
