1. If a section or township boundary has a deflection in alignment, what would we call this 
boundary line?

 a. Governing line
 b. Sectional guide meridian
 c. Sectional correction line
 d. Irregular exterior

2. What may create such a misalignment? 

 a. Parts surveyed from different directions.
 b. Declination vernier out of adjustment.
 c. Previous retracement.
 d. Running a random line with deflection angles.

3. If a corners is lost along such a boundary, what assumption must we make regarding any 
retracement?

 a. The record distances and bearings were run.
 b. There is no error in the record.
 c. The record is in error and we must correct it.

4. On a meridional line, the latitude of the closing distance is distributed among the 
courses in:

 a. Proportion to the length of the tie.
 b. Proportion to the departure of each course.
 c. Proportion to the latitude of each course.

5. Applying the  single proportion concept and the "compass rule," complete the following formulas using the labels in this diagram:

A.  a. D  b. d1  c. L  d. D1
B.  a. D  b. D1  c. L  d. d1
C.  a. D  b. L1  c. L  d. D1
D.  a. D  b. d1  c. L  d. D1

6. What special consideration must be applied when resurveying a township or boundary line that runs east or west?

 a. Correction for curvature of the earth (geodesy)
 b. Errors in the record
 c. Index correction

7. Here is a township border with a lost corner. A retracement using record data was run. Compute the proportional bearings and distances.
