How to replace the red with easy english to make it easier for my students.

[v0031]

Hundreds of drones（无人机） light up Seoul sky with virus messages as the world fights COVID-19.
Three hundred drones were programmed to form pictures above the Han river -- which runs through the South Korean capital -- for the eyecatching flash mob (快闪).
The show began with messages reminding people of key protective methods, including wearing masks, washing hands and keeping a two-meter distance from others.
The drones created pictures of a mask surrounded by coronavirus particles, quickly shuffling to form two hands and water droplets against the dark night sky.
The 10-minute show shifted to messages of thanks for medical workers in the frontlines of the pandemic as well as all South Koreans for their collective work.
"THANKS TO YOU," the drones wrote in the sky next to a heart shape, then formed a map shape of the Korean peninsula（半岛） with the message: "Cheer up, Republic of Korea."
The government-organized event on Saturday night was not advertised in advance in consideration of social distancing rules, one government officer said.

"There wasn't any advertising for the government-organized event on Saturday night because of social distancing rules, one government officer said."

The government-organized event on Saturday night was not advertised in advance beforehand in consideration of social distancing rules,

Any effort to replace "in consideration of" would likely either be extremely wordy or change the meaning slightly. "Because of" is probably the best replacement , but that would suggest the rules required the lack of advertising rather than worries that advertising might cause people to break social distancing rules .

Thank you.
And with your help, I design the following questions for my students.
The process ,from searching the suitable materials to designing questions, is also a self-improvement to me, because I read a lot from the native websites.
