The answer is A. Root crops, including yams, sweet potatoes, and taro, became more common.
The root crops became more common, and practically the basic food source. This was due to the fact that the climate and soil on the Pacific islands were excellent for growing them, and of course for having a sustainable food source.
It is a completely false statement that generally, the compaction of soil is a positive phenomenon. The correct option among the two options that are given in the question is the second option. It is hard to work and manage such type of soils. The loose soils absorb water and minerals very easily, while compacted soil is derived of pores and so absorption is difficult.<span />

Answer:
The building will vibrate around one particular frequency known as its natural, frequency, the building and ground share the building frequency its said to be in resonance.
Explanation:
- Resonance is the frequency of the system to oscillate with a greater velocity than the others as all buildings have a resonance period which is the number of seconds for a building to vibrate and the ground also shows the seismic resonance frequency, the mismatch of the resonance and the wave frequency. Thus taller buildings will be damaged more than shorter structures.
- <u>These forces create the lateral accelerations that scientists measure by the G-forces. The sudden movement creates enormous stresses for the building's structure, including the beams, the columns, and the walls and the floors, as well as the joints that hold them together. If that stress is large enough, the building can collapse.</u>
Answer: 7
Explanation: JN=14 as well as LN. OL is half of LN so you divide 14 by 2
