Explanation:

Statement 1 is correct because Europe at best can be described as the peninsula of Eurasian continent. No part of Europe id far from the moderating influence of the sea as it has penetrated deep in to inland in from of seas like Agean, Gulf of Bothnia etc.
Gulf Stream is mainly responsible for the milder climate of Europe. The Gulf Stream is a major current that runs in a clockwise fashion from the Gulf of Mexico, up the Atlantic Coast of the United States, and then across the Atlantic to Europe. The Gulf Stream is made up of very warm water.  It brings that water to the northern latitudes of Europe.  The Gulf Stream brings warm and humid air to the countries of much of Northern Europe.  By doing so, it allows those countries to have milder climates than those of countries at similar latitudes in other parts of the world.  
The westerlies since blow from southwest have a moderating influence, and there is no North South mountain system in Europe that blocks these winds.
For Example, Europe, which is located at much higher latitude than most of New England (Canada), but experiences much milder weather

2nd statement is incorrect because longitude has no relation with climate.
