Question

read the excerpt from ships chronometer from hms beagle. just as people adopted a common standard time, so numerous aspects of working and daily life were becoming rigidly fixed by the clock, from clocking on at work to school hours and tea - time - which is the subject of our next chapter. what context clue best helps readers determine the meaning of the word standard? numerous rigidly fixed tea - time subject

Explanation:

The phrase "rigidly fixed" implies something is set in a definite, unchanging way, which is similar to the idea of a "standard" being a fixed or established norm. "Numerous" just means many, "tea - time" is a specific time for tea, and "subject" refers to a topic. None of these convey the meaning of "standard" as well as "rigidly fixed".

Answer:

"rigidly fixed"
