Cannot relate warnings upon running dhclient

Good afternoon.

For a long time already, dhclient gives me two warnings upon running Code:rosalind@dna:~$ sudo dhclient -dEvery run succeeds, though; therefore I have ignored the situation until now.

Here is the beginning of the output:
Code:Internet Systems Consortium DHCP Client 4.4.1

/etc/dhcp/dhclient.conf line 16: expecting a statement.

^
/etc/dhcp/dhclient.conf line 35: semicolon expected.

(...)And here is the *complete* configuration-file /etc/dhcp/dhclient.conf". Most of the content are the original commented sections. I highlight the two lines 16 and 35 (1 curly bracket, only) from the console-output:

Code:# Configuration file for /sbin/dhclient.
#
# This is a sample configuration file for dhclient. See dhclient.conf's
# man page for more information about the syntax of this file
# and a more comprehensive list of the parameters understood by
# dhclient.
#
# Normally, if the DHCP server provides reasonable information and does
# not leave anything out (like the domain name, for example), then
# few changes must be made to this file, if any.
