Question
Read the following passage about obtaining rubber from bark-shavings, and identify its text structure.
Where the scrap is removed from the edge of the bark on each occasion before tapping, the amount of rubber to be extracted from the dry shavings is very small—so small, in fact, that when the price of rubber is low, it is doubtful whether it pays to collect and work the material.
On the other hand, where trees are not “scrapped” before tapping, the bark-shavings and tree-scrap are collected together, and the amount of rubber derived from the mixture may be 30 to 40 per cent - upon the gross weight—depending chiefly upon the quality of the tapping (i.e., in this case, the thickness of the paring).

The text structure of the passage you provided is **compare and contrast**. The passage discusses two different methods of obtaining rubber from bark-shavings: one where the scrap is removed before tapping (resulting in minimal rubber extraction) and another where the trees are not scrapped before tapping (resulting in a higher percentage of rubber derived from the mixture). The passage examines the differences in rubber yield and economic viability between the two methods.
