A grass
B. trees
C. flowers
D. cacti
Please select the best answer from the choices provided
A
B
C
D

B. trees

Explanation:

The word "reforestation" itself actually means resupplying or replanting trees in an area that has previously been depleted of trees. From that hint, we can definitely see B as a very likely answer.

"Desertification" is when an area becomes a desert. In order to re-establish the previous flourishing, non-desert ecosystem, trees must be planted.

The answer is thus B.

B

Explanation:

China created a program called Grain for Green in 1999. Through this program, they have reforested about 32 million hectares of land.

Reforest means to replant an area with trees, or to cover an area with forest. China is reforesting, therefore they are planting trees.

So, choice B: trees is correct.

question - in 1827, john walker, a druggist in a small english town, tipped a splint with sulphur, chlorate of potash, and sulphid of antimony, and rubbed it on sandpaper, and it burst into flame. the druggist had discovered the first friction-chemical match, the kind we use to-day. it is called friction-chemical because it is made by mixing certain chemicals together and rubbing them. although walker's match did not require the bottle of acid, nevertheless it was not a good one. it could be lighted only by hard rubbing, and it sputtered and threw fire in all directions. in a few years, however, phosphorus was substituted on the tip for antimony, and the change worked wonders. the match could now be lighted with very little rubbing, and it was no longer necessary to have sandpaper upon which to rub it. it would ignite when rubbed on any dry surface, and there was no longer any sputtering. this was the phosphorus match, the match with which we are so familiar. according the paragraph what was the benefit of the new phosphorus match? it burst into flame when rubbed on sandpaper. it was made by mixing chemicals. it could be ignited on any dry surface. it threw fire in all directions.

answer - matches required natural chemicals
