I'm working with the following [Google Sheet](https://docs.google.com/spreadsheets/d/1s8krJ7rbZ1DMblZ3vdLcG5pySVM3ESCBy1o7R5Zv4LM/edit#gid=237012432).

`Sheet2` uses the following `QUERY()` function to retrieve data from `Sheet1`

`=QUERY(IMPORTRANGE("1s8krJ7rbZ1DMblZ3vdLcG5pySVM3ESCBy1o7R5Zv4LM", "Sheet1!B3:D"))`

Is it possible to return the Row Totals (*For Example:* `B4+C4+D4` *for Row 4*) using the above `QUERY()` function?

Please Advise.

*My Query and Expected Output are Outlined on the Google Sheet.*
