某同学设计了测定气体摩尔体积的探究实验，利用氯酸钾分解制O2。
实验步骤如下：
①把适量的氯酸钾粉末和少量二氧化锰粉末混合均匀，放入干燥的试管中，准确称量试管和药品的总质量为15.95 g。
②连接好实验装置，检查装置的气密性。
③加热，开始反应，直到不再有气体产生为止。
④测量排入量筒中水的体积为285.0 mL，换算成标准状况下氧气的体积为279.7 mL。
⑤准确称量试管和残留物的质量为15.55 g。
根据上述实验过程，回答下列问题：
(1)如何检查装置的气密性？ ____________________________________。
(2)以下是测量收集到气体体积必须包括的几个步骤：
①调整量筒的高度使广口瓶和量筒内的液面高度相同
②使试管和广口瓶内气体都冷却至室温
③读取量筒内液体的体积
这三步操作的正确顺序是_______________(请填写步骤代码)。进行③的实验操作时，若仰视读数，则读取氧气的体积________(填“偏大”“偏小”或“无影响”)。
(3)实验过程中产生氧气的物质的量是________mol；实验测得氧气的摩尔体积是________(保留小数点后两位)。

The questions in this group are based on the content of a passage. After reading the passage, choose the best answer to each question. Answer all questions following the passage on the basis of what is stated or implied in the passage.
While most people agree that the Golden Age of comic books began with the introduction of Superman in 1938 in Action Comics #1, there is less agreement about when exactly the Golden Age ended. There is a general consensus, however, about the factors that brought the Golden Age to a close: the rise of the horror comic book in the late 1940s, and the resulting backlash against comic books in the early 1950s.
Superhero comic books reached their peak of popularity in the early 1940s because of all the GIs in Europe and Japan who eagerly read about Superman, Batman, and The Spirit. When these soldiers came home, they still wanted to read comic books, but they sought out more adult content. William Gaines of EC Comics was happy to meet the market demand with such grim and gritty titles as Weird Fantasy and The Crypt of Terror. The creators of superhero comic books, not wanting to be left behind, responded by matching their protagonists against darker criminals in more violent encounters.
These darker comic books aroused the anger of child psychologist Fredric Wertham, who believed that comic books were leading the nation’s youth into crime, violence, and drug abuse. Wertham’s book, The Seduction of the Innocent, was a national best-seller that helped bring about congressional investigations into the corrupting influence of comic books. The Senate committee that reviewed Wertham’s charges decided to create the Comics Code Authority, a regulatory body that prohibited comic books from mentioning sexuality, alcohol, drugs, criminal behavior, or any themes related to the horror genre.
These regulations had a numbing effect on the industry. EC Comics was nearly driven out of the comics business, and the other major players canceled many of their most prominent titles. The comics business did not recover until the Marvel revolution of the early 1960s ushered in the Silver Age.
According to the passage, what can we infer to be the central message of Fredric Wertham’s The Seduction of the Innocent ？（）
A. Adults reading violent comic books were as likely to be corrupted by them as young people were.
B. The horror comic books of the late 1940s were inferior to the superhero comic books that gained popularity during World War Ⅱ.
C. Comic books were leading the nation’s youth into crime, violence, and drug abuse.
D. Creating a regulatory board to censor the comic book industry would drive the worst offenders out of the business.
E. Comic books would never be able to convey stories of any serious literary merit.
