Statement 1 and 2 are falsifiable while that of statement 3 to 6 are not falsifiable.

Explanation:

As the statements are not given, the statements to be classified are as below

First two statements are Falsifiable as the reasons are below

As for these two statements there are counter facts/cross checking facts from which the truthfulness of the statements can be identified. For the 1st statement, the historic facts can be used and for the 2nd statement, the medical records for the death of  Kennedy can be used to test the claim

the berlin blockade was an international crisis that arose from an attempt by the soviet union, in 1948–49, to force the western allied powers (the united states, the united kingdom, and france) to abandon their post-world war ii jurisdictions in west berlin. in march 1948 the allied powers decided to unite their different occupation zones of germany into a single economic unit. in protest, the soviet representative withdrew from the allied control council. coincident with the introduction of a new deutsche mark in west berlin (as throughout west germany), which the soviets regarded as a violation of agreements with the allies, the soviet occupation forces in eastern germany began a blockade of all rail, road, and water communications between berlin and the west. on june 24 the soviets announced that the four-power administration of berlin had ceased and that the allies no longer had any rights there.

the main concern with the first draft of the articles of confederation was too much power in the state governments.
