Question: Question: "Which timeline is formed without any qualification or condition?" Context: "The problem of the flow of time, as it has been treated in analytic philosophy, owes its beginning to a paper written by J. M. E. McTaggart. In this paper McTaggart proposes two "temporal series". The first series, which means to account for our intuitions about temporal becoming, or the moving Now, is called the A-series. The A-series orders events according to their being in the past, present or future, simpliciter and in comparison to each other. The B-series eliminates all reference to the present, and the associated temporal modalities of past and future, and orders all events by the temporal relations earlier than and later than." Answer:
Answer: A-series

Question: Question: "What is the main difference mentioned between the two systems?" Context: "The Weston Cadet (model 852 introduced in 1949), Direct Reading (model 853 introduced 1954) and Master III (models 737 and S141.3 introduced in 1956) were the first in their line of exposure meters to switch and utilize the meanwhile established ASA scale instead. Other models used the original Weston scale up until ca. 1955. The company continued to publish Weston film ratings after 1955, but while their recommended values often differed slightly from the ASA film speeds found on film boxes, these newer Weston values were based on the ASA system and had to be converted for use with older Weston meters by subtracting 1/3 exposure stop as per Weston's recommendation. Vice versa, "old" Weston film speed ratings could be converted into "new" Westons and the ASA scale by adding the same amount, that is, a film rating of 100 Weston (up to 1955) corresponded with 125 ASA (as per ASA PH2.5-1954 and before). This conversion was not necessary on Weston meters manufactured and Weston film ratings published since 1956 due to their inherent use of the ASA system; however the changes of the ASA PH2.5-1960 revision may be taken into account when comparing with newer ASA or ISO values."

Question: Question: "The AlpTransit project aims to achieve their goal through?" Context: "The most dense rail network in Europe of 5,063 km (3,146 mi) carries over 350 million passengers annually. In 2007, each Swiss citizen travelled on average 2,258 km (1,403 mi) by rail, which makes them the keenest rail users. The network is administered mainly by the Federal Railways, except in Graubunden, where the 366 km (227 mi) narrow gauge railway is operated by the Rhaetian Railways and includes some World Heritage lines. The building of new railway base tunnels through the Alps is under way to reduce the time of travel between north and south through the AlpTransit project." Answer:
Answer:
building of new railway base tunnels through the Alps
