All 55 delegates that attend the constitutional convention signed the final document true or false

No this statement is not true.  

Explanation:

According to the right statement, all the 55 delegates who attended the constitutional convention did not sign the final document but only 39 signed the final documents.

In this meeting (held at Independence Hall in Philadelphia, Pennsylvania) it was decided that to run the state in a very sting and effective manner, there is a need to form a new and strong government instead of amending the existing articles of confederation.  

union blockade

explanation:

the union blockade in the american civil war was a naval strategy by the united states to prevent the confederacy from trading.

the blockade was proclaimed by president abraham lincoln in april 1861, and required the monitoring of 3,500 miles (5,600 km) of atlantic and gulf coastline, including 12 major ports, notably new orleans and mobile. those blockade runners fast enough to evade the union navy could only carry a small fraction of the supplies needed. they were operated largely by british citizens, making use of neutral ports such as havana, nassau and bermuda. the union commissioned around 500 ships, which destroyed or captured about 1,500 blockade runners over the course of the war.
