The Reasoning Book is an embarrassment to the org. It only made sense because of the old generation teaching and I cant believe it wasnt deleted from the online library years ago.
Regarding the last days it still says (from jw.org):
Last Days
Definition: The Bible uses the expression “last days” to refer to the concluding time period leading up to a divinely appointed execution that marks the end of a system of things. The Jewish system with its worship built around the temple in Jerusalem experienced its last days from 33 to 70 C.E. What occurred then was pictorial of what would be experienced in a greatly intensified way and on a global scale at a time when all nations would be facing the execution of judgment decreed by God. The present wicked system of things, which extends worldwide, entered its last days in 1914, and some of the generation alive then will also be on hand to witness its complete end in the “great tribulation.”
Here is the ridiculous explanation for 'increased' earthquakes:
“There will be great earthquakes” (Luke 21:11)
It is true that there were major quakes in centuries past; furthermore, with their sensitive equipment scientists now detect more than a million quakes a year. But no special instruments are needed for people to know when there is a great earthquake.
Has there actually been a significant number of major earthquakes since 1914? With data obtained from the National Geophysical Data Center in Boulder, Colorado, supplemented by a number of standard reference works, a tabulation was made in 1984 that included only earthquakes that measured 7.5 or more on the Richter scale, or that resulted in destruction of five million dollars (U.S.) or more in property, or that caused 100 or more deaths. It was calculated that there had been 856 of such earthquakes during the 2,000 years before 1914. The same tabulation showed that in just 69 years following 1914 there were 605 of such quakes. That means that, in comparison with the previous 2,000 years, the average per year has been 20 times as great since 1914.
