Multimode fibers have large diameter ( about 50-100 microns), and are used for short and medium distance transmission. If long multimode fiber cable are used, it can cause distortion at the receiving end leading to partial data transmission.
Multimode cables are used for local-area network.
Single mode fiber has small diameter of about 8.5-10 microns and can be used to transmit up to 50 times more distance than the multimode. Hence it is used for long distance communication.
The clergy is defined as the 'body of persons including ministers, sheiks, priests, and rabbis who are trained and ordained for religious service.' Thus, the more common tasks performed by them include arranging and directing the religious services along with calling upon and encouraging spirituality amongst people. While the less common tasks carried out by them include assembling and carrying out sermons and studying the religious texts. Thus, options 1, 3, 4, and 5 are the correct options.
