Problem: The interdimensional hypothesis (IDH or IH), is an idea advanced by Ufologists such as Jacques Vallee that says unidentified flying objects (UFOs) and related events involve visitations from other "realities" or "dimensions" that coexist separately alongside our own. It is an alternative to the extraterrestrial hypothesis (ETH).

Based on the paragraph above can we conclude that "Jacques Vallee is not very proud of the interdimensional hypothesis."? OPTIONS:
- Yes
- It's impossible to say
- No

A: It's impossible to say

Problem: Rana amurensis (Khabarovsk frog, Siberian wood frog, Heilongjiang brown frog or Amur brown frog) is a species of true frog found in northern Asia. It ranges across western Siberia, as well as northeastern China, northeastern Mongolia, and on the northern Korean Peninsula and on Sakhalin. "Rana coreana" was previously included in this species as a subspecies.

Based on the paragraph above can we conclude that "Rana coreana was discovered earlier than Rana amurensis."? OPTIONS:
- Yes
- It's impossible to say
- No

A: It's impossible to say

Problem: Galanthus nivalis, the snowdrop or common snowdrop, is the best-known and most widespread of the 20 species in its genus, "Galanthus". Snowdrops are among the first bulbs to bloom in spring and can form impressive carpets of white in areas where they are native or have been naturalised. They should not be confused with the snowflakes, in the genera "Leucojum" and "Acis".

Based on the paragraph above can we conclude that "Snowdrops are harvested in fall."? OPTIONS:
- Yes
- It's impossible to say
- No

A:
No
