Answer to question 1: candle wax
Corresponding to the original text: Paragraph 2: which means that, like candlewax, they melt when heated and can then be reshaped

Corresponding to the original text: Paragraph 5: This remains was then left to cool and harden, and ground up a second time. The resulting granular powder was raw Bakelite
Resolution: locate this sentence according to cool, hardened, and powder. The blank in the stem modifies Bakelite. According to this modification relationship, it is easy to determine that the answer is raw

In the last stage, the heated Bakelite was poured into a hollow mould of the required shape and subjected to extreme heat and pressure
Analysis: null and heat are parallel, but heat appears directly in the original text, so it is easy to lock the answer to pressure
Answer to question 9: B
Corresponding to the original text: Paragraph 6: Moulds had to be carefully designed so that the more Bakelite would flow even and completely into the mold
Resolution: This question uses the way of word meaning interpretation to replace ease with even and completely, and fill corresponds to flow into, so B is determined to be the correct answer.
Answer to question 10: C
The object could not be designed so that it was locked into the mold and there difficulty to extract

Analysis: According to 1907, we located the first and fourth paragraphs, and found that the content of the first paragraph was slightly different from the question stem, so we mainly focused on the fourth paragraph. The synonym of "modern" and "today" in the stem corresponds to "principles" and "features", that is, all information points in the stem can find the basis in the original text, so the answer is "YES"
Answer to question 12: FALSE
Corresponding to the original text: Paragraph 7: Baekeland's invention, although treated with disdain in its early years, went on to enjoy an unparalleled popularity
Analysis: Baekeland's invention in the original text was despised at first, but was later widely welcomed. This conflicts with the immediacy in the question stem, so the answer is FALSE

Corresponding to the original text: Paragraph 7: consumers everywhere related its dazzling array of shades, delighted that they were now, at last, no longer restricted to the wood tones and drab browns of the pre-plastic era
Explanation: The original said that this material has a variety of colors, and people no longer have to be subject to wood color and brown. This conflicts with only in the question stem, so the answer is determined to be FLASE
