What do you mean by 'in this unit'? If we're talking about scientists in general it would be A. curious. Not all scientists are talkative, pessimistic, or wealthy. So, that leaves curious. Because, why would you decide to be a scientist if you're not curious about the world and science?
Answer:
In this short story by Ray Bradbury we can find many technologies similar to those we have today.
Explanation:
Here I will leave a list with the technological items in the story and their similar at present:
- The voice of the clock in the room: Although we do not use a clock that tells us "time to get up" over and over again, it is very common to have an alarm clock with some personalized sound, we can even put some song for the cell phone alarm.
- The breakfast oven that prepares the toasts: Today there are microwaves that you can program with a timer to turn them on.
- The voice that speaks about the news and the bills pending payment: This could be similar to the alarms or reminders that we program on our cell phone, where we can write down from birthdays to due dates of bills.
- The automatic garage door: Today there are automated doors that open at the push of a button.
- The dishwashing machine: That exists today, with the only difference that each person must put dirty dishes there.
- Mechanical mice: What resembles this today are electric vacuum cleaners, also programmable that one can leave to vacuum the house on their own.
- The garden water jets: This is also something that is used today.
