False, Time Series methods base forecasts only on past variables and not on recent values.
Forecasting in time series is done when we make scientific predictions based on historical data. Time series involves building models through the analysis of historical data and using them to make observations that help in decision-making. The methods of time series refer to the different ways to measure the timed values.
There are four different components of the methods of time series. The first one is a secular trend which helps to describe the movement along the term. The second one is seasonal variations that help to show seasonal changes. The third one is cyclical fluctuations that correspond to periodical changes. the last component is irregular variations that happen at random.

<u>Answer:
</u>
Gravity causes stars to form out of gas clouds
.
<u>Explanation:</u>
The formation occurs in molecular clouds in the interstellar space. The atoms of light are first forced under sufficient pressure so that their nuclei undergo fusion. The gravitational force is responsible for this fusion to begin.
The gases present in these clouds clump to form molecules with higher densities. Due to the internal gravitational disturbance, there begins to occur a collapse of the denser regions of the cloud. As the collapse continues to occur, the temperatures begin to increase and each of the smaller clouds will eventually form a star.
The correct answer is C. Collective Security.
Explanation
Collective security is a concept that refers to a type of political alliance between countries that agree to maintain security among all. Therefore, they undertake to act collectively when there is a threat to any of them. This idea is related to the phrase in the fragment "The parties agree that an attack against one or more of them shall be considered an attack against all." So the correct answer is C. Collective Security.
