My father is an electrician.

My grandfather works in the cultivated field every day.

In this company, he is in the lowest of the low positions.

He misread the word 'denden'.

The rearguard is a role that is positioned at the end of the team.

His house is at the bottom of the mountain.

He put the book on the lower shelf.

He went down the stairs.

He performs best under pressure.
