In the modern world, many countries with kings or queens have evolved into constitutional democracies. in these countries, monarchs are mostly

symbolic

Explanation:

The monarchs of the modern world are not enjoying the same power as they did in the past. While they officially hold their title, they are not the ones in charge in the country, but instead they have a much more symbolic role, performing certain actions which are more of a formality. The loss of power came throughout the 19th and 20th century in most countries in the world, where the monarchies were replaced by other systems, but because of their historical and cultural importance, the monarchs were allowed to retain their titles, just with much more limited power and authority.

i decided to stay late in the laboratory to continue my experiment with the lightbulb. at midnight, thomas edison opened the door and walked in with his head held high.

1. he leaned on the wall and observed me carefully.

2. his harsh scrutiny made me self-conscious of my skills in the lab.

3. perhaps it was just me, but the air in the laboratory began to thicken as i found myself having difficulty to breathe.

4. i turned to look at him fully as i mentally prepared myself for what my very first words would be to thomas edison.

5. the next couple of seconds shocked me. it wasn't me who spoke, but rather him and with diction i could never think of using in a simple sentence.
