ld manual and alignment

[ali hagigat]

3.6.3 Output Section Address
The alignment requirement of the output section is the strictest
alignment of any input section contained within the output section.
--------------------------------------------------------

I have copied part of GNU ld (linker) manual. I have two questions:
1)  What "the strictest alignment of any input section" mean? The
alignment of input sections are different?
2) My binutils package is:
Name        : binutils                     Relocations: (not relocatable)
Version     : 2.21.53.0.2                 Vendor: Fedora Project
Release     : 1.fc17
What is the alignment of the input sections?
