13. A dogleg may be described as one or more of the following: (1) a reverse bend, (2) a full
throw at a station, (3) a negative ordinate, (4) a half throw at a station.
A.
Only (1) and (2).
B.
All but (4).
C.
Only (1) and (3).
D.
All but (3).

14. When adjusting the proposed ordinates for the actual curve described in the text to make the
final throw a zero, those at stations 4 and 18 were adjusted. Another pair of stations that
could have been used is stations:
A.
3 and 24.
B.
5 and 13.
C.
6 and 20.
D.
10 and 26.

15. On sheet 1 of annex A, Sta. 2 reads "+5," which means the measured ordinate is:
A.
5/8 of an inch.
B.
5 inches.
C.
5/8 of a foot.
D.
5 feet.

16. You have measured the ordinates and calculated the throws for a 72-station curve, and you
find that the last half throw is +4. The best way to correct this is to:
A.
Add 1 to the ordinate at station 44 and subtract 1 at station 48.
B.
Add 1 to the ordinate at station 27 and subtract 1 at station 29.
C.
Add 2 to the ordinate at station 65 and subtract 2 at station 67.
D.
Subtract 1 from the ordinate at station 36 and add 1 at station 40.
