Correct Answer: A. a quatrain

Correct Answer: B) Exoskeleton

Explanation

The question is asking which type of skeleton is most appropriate for a cockroach. The options are hyrostatic, exoskeleton, endoskeleton, cartilaginous, and bonny skeleton. A skeleton is a framework that provides support and shape for an organism's body. The cockroach has an exoskeleton, which is a hard, protective outer covering that encases its body. This exoskeleton is made up of a tough material called chitin, which provides protection against predators and environmental factors. Hyrostatic skeletons, such as those found in worms, use fluid pressure to provide support and allow for movement. Endoskeletons, such as those found in humans, are internal skeletons that provide support for the body. Cartilaginous skeletons, such as those found in sharks, are made up of cartilage and provide support and flexibility. Bonny skeletons are not a type of skeleton, so option E is incorrect. Therefore, the most appropriate type of skeleton for a cockroach is an exoskeleton, which provides protection and support for the insect's body. Option B is the correct answer.

Adah's first day at the Methodist school is a significant event in the plot development of 'Second Class Citizen'. It marks the beginning of Adah's journey towards self-discovery and independence. The school serves as a platform for Adah to escape from her oppressive home environment and to explore her intellectual capabilities. Her experiences at the school, including her interactions with her teachers and peers, shape her character and influence her future decisions.

Therefore, Adah's first day at the Methodist school contributes significantly to the development of the plot.

Correct Answer: C. three weeks

Correct Answer: D. 13³/₅cm

Explanation

Perimeter of sector = \(\frac{\theta}{360°} \times 2\pi r + 2r\)

= \(\frac{108}{360} \times 2 \times \frac{22}{7} \times \frac{7}{2} + 2(\frac{7}{2})\)

= \(6 \frac{3}{5} + 7\)

= \(13 \frac{3}{5} cm\)
