The answer that best fits the blank is ISOLATED FROM. Those technology skills and subject-specific skills that are separated from the rest of the curriculum are being taught using the school computer laboratories. Technology skills include skills that use computers or machines such as web design, email management, database and spreadsheets, and etc.
I don't know technology, but using Satellite images, we are able to see that the continents once fitted into one 'jigsaw'. This shows that the continents must have drifted to its original place. Furthermore, Geothermal stations have pointed out convection currents in the Earth's mantle has caused the movement of crusts.
Explanation:
Concatenation allows you to add multiple strings together to form one long string by using the '+' operator between each string, so the purpose of concatenation is "<em>to combine two or more strings into one big string</em>" (third option).

I'd go with two answers.
A: To permanently remove a file from her computer, Sarah doubled-clicked on the My Computer icon and searched for her file under the “Uninstall or change a program” menu option.
Or
B: Empty the Recycle Bin.
This question is somewhat not clear. Why I went with the answers above is because I really do not know what kind of a file Sarah wants to permanently remove. You can permanently delete a program file installed in the computer by following the procedure in option A. The option above will take you to the control panel and you'll be able to select the program you'd want to permanently remove. If you had initially deleted a file like a picture or a document or anything else that you necessarily do not need, it will go to recycle bin. You can head over there and select the Empty the Recycle Bin option to permanently delete the file.
